|What is Octave|
GNU 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 Matlab. It may also be used as a batch-oriented language.
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 Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.
Octave is available from http://www.gnu.org/software/octave/

Note, as this program plots a graph, you must have X11-forwarding enabled on your X-terminal session. See the Access (original) page for more information.
An Octave MPI toolbox is also available. The following script illustrates how it can be used to run one of the examples which comes with it:
