If memory serves me correctly this gives an overall gain factor somewhere close to 1/8 (maybe 10% or so). Share. It is somewhat missing the point to talk about how Dot fails as matrix multiplication. The point of Dot is that it is a tensor operation and that it sometimes corresponds to matrix multiplication. In terms of tensor indices, Dot contracts the right-most index of the first entry with the left-most index of the second. We call this matrix the 3 ⇥ 3 identity matrix. ***** *** Matrix multiplication You can “multiply” two 3⇥3matricestoobtainanother3⇥3matrix.
