The one time I tried something similar (implementing a signal
processing function in Python), I found NumPy to be _significantly_
faster -- which makes sense, since all of the matrix arithmetic was
implemented in hard coded, compiled C code instead of interpreted byte
code.--wpd -- http://mail.python.org/mailman/listinfo/python-list
