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

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

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