Stable and works.
This is awesome software! Using GPUmat on Nv670 I get speed-ups between x8 and x10 over a 4 core Phenome system for a method working on large dissimilarity matrices. I tried to combine with GNU/octave but failed despite of relocating mex files - I think octave support should be possible without major efforts. This would be fantastic. Anyway thanks so much to the developers for their great work! ... (PS.: would you like to support the sign() and bsxfun() functions in future?)
gpumat works great
