GNU Octave

If you're in need of a high-level language perfect for numerical computation, look no further than the GNU Octave project. This software provides a convenient command line interface that can solve both linear and nonlinear problems numerically, and it can be used for a variety of numerical experiments using a language that's mostly compatible with Matlab. Additionally, Octave has extensive tools that can help you solve common numerical linear algebra problems, as well as find the roots of nonlinear equations. You can use it for integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations.

One of the best things about Octave is that it's easily extensible and customizable. You can use user-defined functions written in Octave's own language, or you can use dynamically loaded modules written in C++, C, Fortran, or other languages. And if you're looking for software that's freely redistributable and modifiable, Octave is an excellent choice. In fact, you may redistribute or modify it under the GNU General Public License.

Octave was written by John W. Eaton and many others. Since it's free software, the developers encourage users to get involved by writing and contributing additional functions or reporting any problems. Finally, it's worth noting that Octave includes several built-in variables that contain information about the command line, including the number of arguments and all of the options. If you're in need of robust numerical computation software, GNU Octave is definitely worth considering.
