... matrix produces the same dimension matrix with each element divided by the scalar. Matrix multiplication is a little trickier. If two matrices A and B are to be multiplied, they must be of the right dimension. Matrix multiplication is a legitimate operation if and only if a matrix A with m rows and ...
