there are some license issues between CUDA and Octave, CUDA is mostly
closed source and Octave is GPLv3.

I looked around to find a GPU library with a more open source friendly
license and Brook looks good so far, using a BSD license for most parts.
The CUDA-Matlab plugin only includes a fft function, so it's not that
feature rich.
I don't really know which licenses fit together, would BSD+GPL work?
