I am developing an application for adaptive filtering where I have two matrices A and B.

Matrix A is of order (21 * 1)

Matrix B is of order (23 * 23)

By the rule of matrix multiplication we cannot multiply such a pair of matrices.

Is there any theory which tells how to multiply these.

I found a method for adding such a pair of matrices and hence it occurs to me that there has to be a solution for proposed problem.

thanks
