shogun has interfaces to octave,r,python and matlab and the command
line. sometimes things are more efficient to do in other languages and
well I know of many people trying to get rid of matlab. Some switched to
python, some to octave and it is all a mess when you have to cooperate
with them :)

shogun's? Yes it is GPL3, python uses the python license (more
permissive) and compatible to the gpl too.

thanks a lot for your help,
