## Multiplication of two matrices

The Product AB of two matrices A and B is defined only if the number of columns in A is equal to the number

of rows in B. If A is of order m x n and B is of order n x x. Then order of AB is m x s.

To multiply A with B, elements of the ith row of A are to be multiplied by corresponding elements of jth

column of B and then their sum is taken
