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 packed as a <a href="http://portableapps.com/about/what_is_a_portable_app">portable app</a> so you can do your numerical computations on the go. It has all the same features as Octave, plus, it leaves no personal information behind on the machine you run it on, so you can take it with you wherever you go. <a href="http://octave.org">Learn more about GNU Octave...</a>
