About Octave:

GNU Octave is a high-level interpreted language, primarily intended for 
numerical computations.  It provides capabilities for the numerical 
solution of linear and nonlinear problems and for performing other 
numerical experiments.  It also provides extensive graphics capabilities 
for data visualization and manipulation.  Octave is normally used 
through its interactive command line interface, but it can also be used 
to write non-interactive programs.  The Octave language is quite similar 
to Matlab so that most programs are easily portable.  A full description 
of Octave capabilities is available at 
http://octave.org/doc/interpreter/index.html.
