    [SOLVED] Matrix Multiplication

    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

    There is such a thing as a "Kronecker product." Perhaps this is what you are looking for.
