Octave 3.2.4

Both students and workers in sectors related to mathematics need to have at hand at all times tools that facilitate the calculations of very complex operations that cannot even be executed in the vast majority of calculators.

Octave is a tool that solves algebra problems, functions, polynomials and a long list of the most complex operations. With Octave it is possible to solve mathematical exercises exactly the same as with the Matlab program but with the advantage that this tool is completely free and also allows to export files with functions in format "m".

In short, Octave is the best free option for people who need a powerful tool to solve any possible mathematical problem.
