root #emerge --ask sci-mathematics/octaveOctave packages
Octave's functionality (i.e. selection of functions available to the user in octave) is extended via octave-packages[1], usually provided by octave-forge[2]. There are two ways to install octave packages:
- Use Octave's own pkg command to install missing packages (requires the
curlUSE flag) - Use app-portage/g-octave to generate ebuilds for octave-packages from Octave-Forge and install them via Portage
There is conflicting information about which method to prefer [3] [4], so no recommendation can be given at this point.
