    What do you mean the same way as any other? In what pattern?

    Suppose that we have A_{2,3}~\&~B_{2,3} then it impossible to form A\cdot B.

    But B^T, the transpose is a 3\times 2 matrix.
    Thus A\cdot B^T is a 2\times 2 matrix.

    Well, that would be why I asked, "Why do you ask?" Just trying to make sure we have a good question. If matrices are not conformable, you DON'T multiply them.
