Octave and Matlab are both, high-level languages and

mathematical programming environments for:

   Visualization

   Programming, algorithm development

   Numerical computation: linear algebra, optimization,

control, statistics, signal and image processing, etc.

Beware: Octave/Matlab programs can be slow.

Overview

Matlab-Octave comparison :

   Matlab is more flexible/advanced/powerful/costly

   Octave is for free (GPL license)
