GNU Octave

GNU Octave is a free and open-source computing environment and high-level interactive programming language, that is primarily intended for numerical computations.

Octave packages
Octave's functionality (i.e. selection of functions available to the user in octave) is extended via octave-packages, usually provided by octave-forge. There are two ways to install octave packages:


 * Use Octave's own command to install missing packages (requires the   USE flag)
 * Use to generate ebuilds for octave-packages from Octave-Forge and install them via Portage

There is conflicting information about which method to prefer, so no recommendation can be given at this point.
