Could you go back for a second and describe your problem a little bit more. It sounds like you were doing the wrong operation. By SSE, you mean "Sum of Squared Errors" of the 25000 length-80 vectors, right? In that case, using matrix multiplication won't give you that. That will, in essence calculate the dot-product of each of the 25000 length-80 vectors with *each* of the other 25000 length-80 vectors in addition to themselves. It seems to me like you want something like this: SSE = sum(error * error, axis=-1) Then SSE.shape == (25000,). -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
