Inner product without transposing matrix

Question

Suppose I have a nxm matrix A and nx1 column-vector B. I perform an inner product using transpose(A) * B. This works fine.

However, I would like to not have to transpose A and still get the same result.

Is there a way to get the same result without transposing A (possibly with a transpose of B?)

My linear algebra skills aren't too great. Hoping to get help from the experts here.

What do you mean by "inner product"? Does $A^TB=(B^TA)^T$ help?
That's it @ACARCHAU. Thanks to you both. Mind posting as an answer so I can accept and close the question?

From a comment, $A^TB=(B^TA)^T$

	It would be better to write this using MathJax (LaTex) as Jonas did in his answer. Regards – Amzoti Jan 10 at 22:55
	Cool! I didn't know that one could embed LaTeX in StackExchange posts. – Clayton Stanley Jan 10 at 23:33
	Please see MathJax and FAQ for further details. The MathJax displaying of math is lovely! Regards – Amzoti Jan 10 at 23:50
