Yes. If you don't use any internals of Octave and you do not link to
Octave libraries, but you only use Octave as a black box reading input
and writing output, you can use it in every way you want.
If you distribute Octave together with your application, you must also
distribute the Octave source, or offer to provide it as stated in the
If you use Octave in a commercial product and you do make money from it,
it would be nice to contribute to Octave development with a donation or
other means. And you can also use this an advertisement for you :)
