<tmdoc-title|The Cadabra system>
<hlink|Cadabra|http://www.aei.mpg.de/~peekas/cadabra/> is a computer
algebra system for the manipulation of what could loosely be called
<em|tensorial expressions>. It is aimed at, though not necessarily
restricted to, theoretical high-energy physicists. Because of its target
audience, the program's interface, storage system and underlying philosophy
differ substantially from other computer algebra systems. Cadabra is
developed by <hlink|<name|Kasper Peeters>|http://www.aei.mpg.de/~peekas/>
and distributed under the GPL license.

<tmdoc-title|The <abbr|Dr.> Geo system>
<hlink|<name|<abbr|Dr.> Geo>|http://www.ofset.org/drgeo> is a <name|Gnome>
free software created both for the interactive study of Euclidean geometry
and for a mild introduction to <name|Guile>/<name|Scheme> programming.
Using <name|<abbr|Dr.> Geo>, you can draw many classical geometric
contructions and explore their propperties either from the metric point of
view (measuring angles and length) or from the transformation one (via
plane trasformations). Each <name|<abbr|Dr.> Geo> figure comes with a logic
tree which shows all steps towards its construction. The basic geometric
constructions provided by the software can be extended by the user adding
macro-constructions.
<name|<abbr|Dr.> Geo> also offers the possibility to learn
<name|Guile>/<name|Scheme> programming at a very introductory level. With
<name|Guile> scripts it is easy to interact with the geometric apparatus by
implementing, for example, several formulas. In the latest releases,
<name|<abbr|Dr.> Geo> has been improved on the programming side since it
can evaluate entire files written in <name|Scheme>. In this way the user
can take advantage from the typical structures of a high level language,
like recursive ones for example, to create new kinds of figures.
In <name|<abbr|Dr.> Geo> there are many utilities available to the teacher:
customization and locking of the user interface, integration in
<name|<abbr|Dr.> Geo> of a simple text editor, possibility to export
figures (<LaTeX>, <name|Postscript> and PNG), etc.
Currently, a project is in progress to have a <TeXmacs> plugin for
<name|<abbr|Dr.> Geo>. In this way it will be possible to use <TeXmacs> as
front-end interface for <name|<abbr|Dr.> Geo> and integrate directly all
the geometric figures into scientific documents.

<tmdoc-title|The Eukleides system>
<hlink|Eukleides|http://www.eukleides.org/> is a Euclidean geometry drawing
language. It has been designed in order to be close to the traditional
language of elementary Euclidean geometry. In many cases, it makes possible
to completely avoid the use of Cartesian coordinates.

Some hints about output
</expand>
Among the tools packages supported by <TeXmacs> environment here, some
experiences have to be kept in mind:
<\expand|enumerate-roman>
<item>Maxima and Yacas are the powerful softwares for symbolic
calculation;
<item>Gnuplot and other CAS's can used to plot the graphs in 2D, 3D and
scientific data plots. But the Gnuplot is the best recommended software
since the graph that it generates can be directly embedded into the
worksheet in <TeXmacs>.
<item>Also there are many powerful softwares with numerical abilities in
Linux world, for example: Octave, Lab, Scilab and R (check your "session
options" or the <TeXmacs>_INSTALL/lib exec). But Scilab owns its
"terminal session" which is not easily embedded into the <TeXmacs>,
Octave is the best choice due to its full accessibility.
<item>Output format: Postscript format is the best choice as above
mentioned. For the Windows user and not heard about this format, HTML
format may be the suitable one. But for mathematical document, it is may
be a bad news that directly output the HTML from <TeXmacs> is generally
non-satisfied. If you want to generate HTML files, <LaTeX>2html maybe
have some help. Consider to export <LaTeX> format from <TeXmacs> and use
the following latex2html command to translate <TeX> file into HTML and
picture files:
<\code>
\<gtr\> latex2html -nonavigation -split 0 filename.tex
</code>
if you want only one HTML file with picture files without navigation
icons. Suppose that there are plenty of pictures generated by CAS's in
your <TeXmacs> file, some modifications have to be made by your hand. The
reason is that no PS Tricks implement yet in latex2html and this is just
the <TeX> package used by <TeXmacs> to make in-line Postscript graphs.
First capture the pictures by picture capture program, e.g. ksnapshot or
GIMP, by CAS's in another xterm and save it as eps format. Then edit the
<LaTeX> file, removing all lines including "cat code
<with|mode|math|\<cdots\>>" in presume part and adding the eps graphs as
follows : \
<\verbatim>
<with|mode|math|\<backslash\>>document[12pt]{article}
<with|mode|math|\<backslash\>>package[dvips]{graphics}
\ \ \ <with|mode|math|\<cdots\>>
% remove all the line beginning with "catcode"
\ \ \ <with|mode|math|\<cdots\>>\
<with|mode|math|\<backslash\>>begin{document}
\ \ \ <with|mode|math|\<cdots\>>
<with|mode|math|\<backslash\>>begin{center}
\ \ <with|mode|math|\<backslash\>>resizebox{150mm}{!}{<with|mode|math|\<backslash\>>includegraphics{picture.eps}}
<with|mode|math|\<backslash\>>end{center}
\ \ \ <with|mode|math|\<cdots\>>
<with|mode|math|\<backslash\>>end{document}
</verbatim>
Mainly, add the graphics package and use
<with|mode|math|\<backslash\>>include graphics{} to put the graph. And
use above latex2html commands to translate the contents. The directory
named by its filename will be created with HTML file, and png files.
</expand>
Of course, you can export the worksheet from <TeXmacs> into <LaTeX> format
and remake the file by <TeX> system, for example: te<TeX> or Mik<TeX>.
Don't forget to put TeXmacs.sty in the search tree of <TeX> and execute
<with|color|red|texhash>. This file can be found in the diretory of
$<TeXmacs><with|mode|math|\<backslash\>misc\<backslash\>latex.> Then it
will be no problem to <with|color|red|<LaTeX>> this tex file into
PostScript or PDF format.
If you are interested in <TeXmacs> and CAS, more tm files can be found at:

<expand|tmdoc-title|The GTybalt system>
<hlink|<name|GTybalt>|http://www.fis.unipr.it/~stefanw/gtybalt.html> is a
free computer algebra system which is built on top of <name|GiNaC>, CLN and
a program to interpret C and C++ commands. <name|gTybalt>, which is still
in an experimental stage, is maintained by <hlink|<name|Stefan
Weinzierl>|http://www.fis.unipr.it/~stefanw>. Some of the main features of
<name|gTybalt> are the following:
<\itemize>
<item>Object Oriented: <name|gTybalt> allows symbolic calculations within
the C++ programming language.
<item>Efficiency for large scale problems: Solutions developed with
<name|gTybalt> can be compiled with a C++ compiler and executed
independently of <name|gTybalt>.
<item>Short development cycle: <name|gTybalt> can interpret C++ and
execute C++ scripts. Solutions can be developed quickly for small-scale
problems, either interactively or through scripts, and once debugged, the
solutions can be compiled and scaled up to large-scale problems.

<expand|tmdoc-title|The Guile/Scheme language>
<name|Guile>/<name|Scheme> is a full implementation of the object oriented
and <name|Lisp>-like programming language <name|Scheme>. It has special
support for linking external C or C++ programs. This provides a transparent
way to dynamically extend the language with fast new routines.
<name|Guile>/<name|Scheme> is intended to become the major extension
language for the <hlink|GNU project|http://www.gnu.org> and
<hlink|Gnome|http://www.gnome.org>.
In particular, all high-level <TeXmacs> editing routines have been
interfaced to <name|Guile>. These routines thereby are available to users
who can write extensions to the editor, without going into the C++ code of
<TeXmacs>. In the future, we also wish to implement a port to
<name|Guile-gtk>. This extension of <name|Guile> implements a graphical
user interface via gtk, which makes it possible to create menus, iconbars,
file selectors, etc. in a very simple way.
More information about <name|Guile> can be found at
<\itemize>
<item>The <name|Guile> <hlink|home page|http://www.gnu.org/software/guile>.

<doc-data|<doc-title|<TeXmacs>--maxima interface>>
In this tutorial, we shall discuss how to use the free Computer Algebra
System (CAS) maxima from <TeXmacs>. It should be valid for <TeXmacs>-1.0.5
and maxima-5.9.2.
Let's start <TeXmacs>. We shall use the package <tmpackage|varsession>:
<postscript|c0.png|*5/8|*5/8||||>
This is not strictly necessary, but interactive sessions look nicer with
it. We shall also use <menu|Automatically close brackets>:
<postscript|c1.png|*5/8|*5/8||||>
Now we shall start one of the versions of maxima installed:
<postscript|c2.png|*5/8|*5/8||||>
Also we shall tick <menu|Mathematical input>:
<postscript|c3.png|*5/8|*5/8||||>
If you click the icon looking like ``?'' on the toolbar, <TeXmacs> will
show the maxima manual:
<postscript|c4.png|*5/8|*5/8||||>
It is convenient to clone the window:
<postscript|c5.png|*5/8|*5/8||||>
Then, in one of the windows you return to the buffer which contains the
maxima session (in this case, this buffer is called <menu|no name>):
<postscript|c6.png|*5/8|*5/8||||>
In the other window, you can read the manual. Blue texts are hyperlink;
clicking them displays the corresponding sections of the manual.
Everything is ready for doing calculations. Usual methematical notations
can be used for input expressions to a large extent. Don't forget to use
<key|*> for multiplication; it is not visible, just produces a little
space. Powers are produced using the toolbar or <key|^>; fractions -- by
the toolbar or <shortcut|(make-fraction)>; square roots -- by the toolbar or <shortcut|(make-sqrt)>;
large (automatically resizable) brackets -- by <shortcut|(make-bracket-open "(" ")" #t)> (note that with
our settings this produces both the opening bracket and the closing one,
and the cursor is left between them). You can use greek letters. For
example, <with|mode|math|\<alpha\>> can be produced via the toolbar, by
<key|H-a> (see help for the meaning of the modifier hyper), or by <key|a
tab>. <with|mode|math|\<Gamma\>> means the
<with|mode|math|\<Gamma\>>-function; <with|mode|math|\<pi\>> means ... what
would you think? ... <with|mode|math|\<pi\>>; <with|mode|math|\<gamma\>>
means the Euler constant; <with|mode|math|\<zeta\>> means the Riemann
<with|mode|math|\<zeta\>>-function.
<postscript|c7.png|*5/8|*5/8||||>
The integral sign is produced via the toolbar or by <key|S-F5 I>. If it has
limits, it means a definite integral, otherwise indefinite. Then you write
your integrand, then a space, the differential sign (produced by <key|d tab
tab>), a space, and your integration variable. The form of the result often
depends on parameters; in such cases, maxima asks questions. If you don't
want such interactive queries, you can provide the relevant information
beforehand.
<postscript|c8.png|*5/8|*5/8||||>
You can select some (part of) an output field with the mouse:
<postscript|c9.png|*5/8|*5/8||||>
Then click on an input line, and click with the middle mouse button. The
selected expression is inserted. You can edit it and execute.
<postscript|c10.png|*5/8|*5/8||||>
It is also possible to go to an earlier input line, edit it and press
<key|enter>. The old output below this line will be replaced by the new
one. This is very useful during the first stage of your work, when you
investigate various possible approaches. Using this method too often leads
to a spaghetti-like set of input and output lines, which is difficult to
understand; it is even difficult to reproduce your calculation later.
Here are some definite integrals. The base of natural logarithms
<with|mode|math|\<mathe\>> is produced via the toolbar or by <key|e tab
tab>, and the infinity symbol -- via the toolbar or by <key|@ @>.
<postscript|c11.png|*5/8|*5/8||||>
Sums are similar to integrals. In addition to sums with a lower limit and
an upper one, maxima understands sums with a lower limit like
<with|mode|math|n\<in\>[a,b,c]>, where the symbol <with|mode|math|\<in\>>
is produced by <key|\\ i n enter>. Products are also similar. Binomial
coefficients are produced by <key|\\ b i n o m enter>. They look like
matrices, but differ from them! Therefore, don't try to create them via the
toolbar menu for matrices and other kinds of tables.
<postscript|c12.png|*5/8|*5/8||||>
Note a subtle point: the integral sign (or the sum or product sign) is
considered as a kind of an ``opening bracket'', and there is the
corresponding ``closing bracket'', which is invisible, but it shows where
your integral ends. You can see it in the <menu|Document|View|Edit source
tree> mode as <explain-macro|big\|.>. With out setting of
<menu|Edit|Preferences|Keyboard|Automatically close brackets>, it is
automatically produced after the integral sign when you input it; if you
don't use this mode, you can produce it by <key|\\ b i g tab . enter>.
<postscript|c13.png|*5/8|*5/8||||>
Maxima understands matrices and determinants. They are produced via the
toolbar. New columns and rows are inserted by <shortcut|(structured-insert-right)>, <shortcut|(structured-insert-left)>,
<shortcut|(structured-insert-down)>, <shortcut|(structured-insert-up)>. The imaginary unit <with|mode|math|\<mathi\>> is
produced via the toolbar or by <key|i tab tab>.
<postscript|c14.png|*5/8|*5/8||||>
<postscript|c15.png|*5/8|*5/8||||>
You can inserted some text explaining an input line. To this end, placing
the cursor on this input line, select <menu|Insert text field> from the
toolbar menu:
<postscript|c16.png|*5/8|*5/8||||>
Naturally, this explanation text can be as long as you need, and it can
contain mathematical formulae.
<postscript|c17.png|*5/8|*5/8||||>
And here is a determinant.
<postscript|c18.png|*5/8|*5/8||||>
<postscript|c19.png|*5/8|*5/8||||>
Maxima can solve equations and systems of equations. It returns the list of
solutions.
<postscript|c20.png|*5/8|*5/8||||>
Here we define and plot the function <with|mode|math|f(x,y)=<frac|sin(r)|r>>
where <with|mode|math|r=<sqrt|x<rsup|2>+y<rsup|2>>>.
<postscript|c21.png|*5/8|*5/8||||>
The plot appears in a separate gnuplot window:
<postscript|c22.png|*5/8|*5/8||||>
Here we define a recursive function and trace its execution.
<postscript|c23.png|*5/8|*5/8||||>
You can create a ``sub-session'' within the maxima session. With the cursor
on an input line, select <menu|Fold input field> from the toolbar menu:
<postscript|c24.png|*5/8|*5/8||||>
A sub-session appears; you can edit its title:
<postscript|c25.png|*5/8|*5/8||||>
You can work within this sub-session; it has its own current input line.
<postscript|c26.png|*5/8|*5/8||||>
If you dowble-click on the left bar of the sub-session, it gets folded:
<postscript|c27.png|*5/8|*5/8||||>
Now only its title is visible. This is convenient for long sub-calculations
of your project: you can fold them all, and see only the skeleton of your
calculation. Sub-sessions can be nested. You can unfold them by
double-clicking once more.
Finally, we quit maxima:
<postscript|c28.png|*5/8|*5/8||||>
If you give a presentation, it is convenient to select <menu|Remove all
output fields> from the toolbar menu:\
<postscript|c29.png|*5/8|*5/8||||>
All output lines disappear.
<postscript|c30.png|*5/8|*5/8||||>
It suffices to press <key|enter> on an input line, and maxima will be
re-started. The results will be produced in the presence of your audience,
just by pressing <key|enter> many times.
<postscript|c31.png|*5/8|*5/8||||>
Of course, you can save your work as a .tm file. Next time you start
<TeXmacs> to edit this file, just press <key|enter> at the first input line
to re-start maxima.

<tmdoc-title|The Maxima system>
<hlink|<name|Maxima>|http://maxima.sourceforge.net/> is not only one of the
oldest and best computer algebra systems around, it is also one of the only
general purpose systems for which there is a free implementation. The
current free <name|Maxima> implementation was started by
<hlink|<name|William F. Schelter>|http://www.ma.utexas.edu/users/wfs>. It
is dedicated to his memory. Here follow some features of <name|Maxima>:
<\itemize>
<item>Plotting via netmath over the network.
<item>Computations over network
<item>Well tested on a large array of problems.
<item>Source level Debugger for maxima code
<item>Documentation available as html, texinfo, info, dvi and postscript.
The documentation can be read inside <TeXmacs>.
<item>Easy to extend in fundamentally new ways, because you have complete
access to source, and access to Common Lisp.
<item>Portable to many systems.

GNU <name|Octave> č un clone libero di <name|Matlab>, che puň essere
scaricato da
<\verbatim>
\ \ \ \ http://octave.sf.net
</verbatim>
Si dŕ inizio ad una sessione di <name|Octave> utilizzando
<apply|menu|Insert|Session|Octave>. Qui di seguito viene mostrato come
svolgere delle operazioni di algebra lineare con <name|Octave>, come la
moltiplicazione tra matrici, l'inversione e la diagonalizzazione. Si noti
che č necessario (per il momento) utilizzare il comando <verbatim|tmdisp>
per visualizzare l'output in formato matematico.

<expand|tmdoc-title|The GNU Octave system>
GNU <name|Octave> is a high-level language, primarily intended for
numerical computations. It provides a convenient command line interface for
solving linear and nonlinear problems numerically, and for performing other
numerical experiments using a language that is mostly compatible with
<name|Matlab>. It may also be used as a batch-oriented language.
<name|Octave> has extensive tools for solving common numerical linear
algebra problems, finding the roots of nonlinear equations, integrating
ordinary functions, manipulating polynomials, and integrating ordinary
differential and differential-algebraic equations. It is easily extensible
and customizable via user-defined functions written in <name|Octave>'s own
language, or using dynamically loaded modules written in C++, C, Fortran,
or other languages.
A first experimental interface between <TeXmacs> and GNU <name|Octave> has
been written by <name|Michael Graffam>. Unfortunately, we get little help
from the main <name|Octave> developers for the improvement of the interface
and the integration of patches into the mainline of <name|Octave>. So, if
you like the idea of using <name|Octave> from inside <TeXmacs>, then please
help advertising it.

<expand|tmdoc-title|The Pari system>
<hlink|<name|Pari-gp>|http://www.parigp-home.de> is a software package for
computer-aided number theory. It consists of a C library,
<expand|code*|libpari> (with optional assembler cores for some popular
architectures), and of the programmable interactive <kbd|gp> calculator.
While you can write your own <expand|code*|libpari>-based programs, many
people just start up a <kbd|gp> session, or have <kbd|gp> execute their
scripts. Pari sessions can now be started inside <TeXmacs>.
Originally developed at <hlink|Bordeaux|http://www.cribx1.u-bordeaux.fr/>
by a team led by <hlink|<name|Henri Cohen>|http://www.math.u-bordeaux.fr/~cohen/>,
PARI-GP is now maintained by <name|Karim Belabas> at the <hlink|Université
Paris-Sud Orsay|http://www.math.u-psud.fr/> with the help of many volunteer
contributors.

As suggest, users have better install the newest and binary version, now is
0.5, since it is difficult to compile from source. Moreover, if you install
<name|Qcl> from binary installation, confirm that all the library
directory, <verbatim|lib>, is under the directory at which the binary
<verbatim|qcl> locates.

Utilizzare sessioni di Qcl in <TeXmacs>
</expand>
<name|Qcl> è un linguaggio di programmazione di alto livello e indipendente
dall'architettura per i computer quantistici, con una sintassi derivata dai
linguaggi procedurali classici come il <name|C> o il <name|Pascal>. Questo
permette la completa implementazione e la simulazione di algoritmi
quantistici (includendo componenti classiche) in un formalismo consistente.
L'interfaccia di <TeXmacs> è utile soprattutto per visualizzare in modo
leggibile gli stati quantici. Per maggiori informazioni si veda
<\verbatim>
\ \ \ \ http://tph.tuwien.ac.at/~oemer/qcl.html
</verbatim>
Come consiglio, gli utilizzatori farebbero meglio ad installare la versione
binaria più recente, ora vi è la 0.5, poiché è difficile compilare dai
codici sorgenti. Inoltre, se si installa <name|Qcl> dalla versione binaria,
ci si assicuri che tutta la directory di libreria, <verbatim|lib>, sia
sotto la directory in cui sono posti i file binari <verbatim|qcl>.

GNU <name|R> is an integrated suit of software facilities for data

which many classical and modern statistical techniques have been
implemented. You may download <name|R> from
<\verbatim>
\ \ \ \ http://www.r-project.org

In order to launch an <name|R> session inside <TeXmacs>, use
<apply|menu|Insert|Session|R>. The <verbatim|v()> function can be used in
order to include the contents of the <name|R> graphics window inside your
worksheet.
<\session|r|default>

\<gtr\> Welcome to the TeXmacs interface to R.
To put the current graph in the TeXmacs buffer as an eps use v().
The functions plotv(), linesv(), and pointsv() are provided as a
convenience.
They do the regular function, and then insert the graph.
\;
To change the size of the graph that is inserted to TeXmacs,just adjust
the size of the X11 window.

Utilizzare le sessioni di GNU R in <TeXmacs>
</expand>
GNU <name|R> è un insieme integrato di strumenti software per la
manipolazione dei dati e la visualizzazione grafica. Molte persone
utilizzano R come un sistema statistico. Ma gli sviluppatori preferiscono
pensarlo come uno strumento in cui sono stati implementate molte tecniche
statistiche classiche e moderne. Si può scaricare <name|R> da
<\verbatim>
\ \ \ \ http://www.r-project.org
</verbatim>
Per poter lanciare una sessione di <name|R> in <TeXmacs>, si utilizza
<apply|menu|Insert|Session|R>. La funzione <verbatim|v()>può essere
utilizzata per includere il contenuto delle finestre grafiche di <name|R>
nel proprio foglio di lavoro.
<\session|r|default>
<\output>
\<gtr\> Welcome to the TeXmacs interface to R.
To put the current graph in the TeXmacs buffer as an eps use v().
The functions plotv(), linesv(), and pointsv() are provided as a
convenience.
They do the regular function, and then insert the graph.
\;
To change the size of the graph that is inserted to TeXmacs,just adjust
the size of the X11 window.

<expand|tmdoc-title|The GNU R system>
<hlink|R|http://www.r-project.org/> is a language and environment for
statistical computing and graphics. It is a GNU project which is similar to
the S language and environment which was developed at Bell Laboratories by
J<name|ohn Chambers> and colleagues. R can be considered as a different
implementation of S. There are some important differences, but much code
written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear modelling,
classical statistical tests, time-series analysis, classification,
clustering, ...) and graphical techniques, and is highly extensible. The S
language is often the vehicle of choice for research in statistical
methodology, and R provides an Open Source route to participation in that
activity.
A first experimental interface with <TeXmacs> has been written by
<name|Michael Lackmann>. This allows you to use R interactively inside
<TeXmacs> and to easily include tables and the high quality plots from R
into your scientific papers.

<expand|tmdoc-title|The <TeX>/<LaTeX> system>
<TeX> (= tau epsilon chi, and pronounced as "tecch") is a computer language
for use in mathematical typesetting, developed by <abbr|D.E.> <name|Knuth>
from the late 1970s until the late 1980s. The main aim was to provide
output with a typesetting quality that you would expect in nicely printed
books. In the meantime, D.E. <name|Knuth> also developed <name|Metafont>, a
tool to automatically generate nice looking (mathematical) character fonts.
In the 1980s and 1990s <TeX> has been extended by many people, given rise
for instance to <LaTeX>, <name|Ams><TeX> and so on. Current <TeX>
distributions usually contain all these different programs.
In order to use <TeXmacs>, it is assumed that you have installed a <TeX>
system on your system, although <TeXmacs> really only uses the
<name|Metafont> program to generate its fonts. At the moment, <TeXmacs>
also needs the <name|Bib<TeX>> program for generating bibliographies.
More information about the <TeX> system can be found at

A nice feature of <name|Xfig> is that you may include <LaTeX> formulas in

<TeXmacs>, which will call <LaTeX> to transform the <LaTeX> formula into

<expand|tmdoc-title|The Yacas system>
<hlink|<name|Yacas>|http://www.xs4all.nl/~apinkus/yacas.html> is, as it's
name suggest, yet another computer algebra system. Things implemented
include: arbitrary precision, rational numeric, vector, complex, and matrix
computations (including inverses and determinants and solving matrix
equations), derivatives, solving, Taylor series, numerical solving (Newtons
method), and a lot more non-mathematical algorithms. The language natively
supports variables and user-defined functions. There is basic support for
univariate polynomials, integrating functions and tensor calculations.
<name|Yacas> is still under development.
