WebSuppose that A and B are m n and n m matrices, respectively. Then E := AD and F := DB are well de ned matrices of dimensions m n and n m, respectively. By the law of matrix multiplication, their elements are e ij = X n k=1 a ik kjd jj = a ijd jj and f ij = X n k=1 ikd iib kj = d iib ij Thus,post-multiplying A by D is thecolumnoperation WebEven though determinants represent scaling factors, they are not always positive numbers.
