Implementation: Python3 Web26 iul. 2010 · With MULTIPROD the six matrices in A can be multiplied by those in B in a single intuitively appealing step: C = MULTIPROD (A, B). where C is (2×3)×6. By automatically applying AX, MULTIPROD can multiply a single matrix by all the blocks of a block array. So, if. then C = MULTIPROD (A, B) yields a (2×3)×1000×10 array.
