Re: [Numpy-discussion] matrix multipln takes too much time

on my computer I have: 1. 15.6 sec with your code 2. 0.072 sec with resultmatrix2 3. 0.040 sec with tensordot (resultmatrix3) (-- which is a 400x speed)

wow ,thanks! the tensordot fn is blinding fast.. i added /modified resultndarray = tensordot(matrixone[:sample,:], matrixtwo.T, axes=1).T resultmatrix =matrix(abs(resultndarray)) so i can get rid of the negative values in a real case ..your replies helped a lot guys,thanx a lot and happy X'Mas dn
