How do you multiply matrices with:

2. ## Re: Multiplying matrices

Same as any other. Why do you ask?

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.

Thanks for the reply. I have managed to solve this one.
