Just a tiny followup, which may be important unless you carefully read the documentation. The "*" operator doesn't do matrix multiplication for normal numpy arrays - you do need to use its special matrix type to get this. You can use the dot function to get matrix multiplication with its normal arrays. Jeremy -- Jeremy Sanders http://www.jeremysanders.net/ -- http://mail.python.org/mailman/listinfo/python-list
