Unfortunately the Matlab scripts that are floating around the net do not contain the license information. (e.g. takasila.coe.psu.ac.th/~s4810685/DSP/proakis/PWS_DSP/dir2cas.m ) So I don't know if it sufficient to consider the "public domain"... Additionally Python is simply different and allows some thing to do in different (better?) way. In fact I have almost finished the simple dir2cas.py converter. I'll post the source as soon, as it is ready. -- Regards, WZab -- http://mail.python.org/mailman/listinfo/python-list
