If the ultimate dot() call inside tensordot() is one of the above forms, then yes. If it's a 3D-3D product, for example, or one where the shape manipulations leave the arrays discontiguous, then no. -- 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 _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
