<\body> GNU 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 . It may also be used as a batch-oriented language. 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 's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages. A first experimental interface between and GNU has been written by . Unfortunately, we get little help from the main developers for the improvement of the interface and the integration of patches into the mainline of . So, if you like the idea of using from inside , then please help advertising it. <\initial> <\collection> <\references> <\collection> > > > > > > > > > > > > > > > > > >
