What definition of matrix multiplication is that?? If you really want a scalar product, ask for it:: >>> import numpy as np >>> m1 = np.mat('0 1 2') >>> m2 = m1.T >>> np.dot(m1.flat,m2.flat) 5 Alan Isaac _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
