Matrices are 2d only. The * are ** operators have matrix definitions instead of element-by-element definitions. Matrix subarrays are always 2d ... Matrices have an A attribute to return an array view of the data. (Useful for element by element operations.) hth, Alan Isaac _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
