Thank you; this appears to be one of those packages where a good bit of the documentation is in the mailing list :) Or waiting in the typing fingers of the experts for somebody like me to ask at the right time :) Someday perhaps I'll find the time to go through the code and learn what else is there that's not in the pdf book. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
