# Inner product without transposing matrix

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.

transpose( transpose(B) * A ) –  ACARCHAU Jan 10 '13 at 4:31
What do you mean by "inner product"? Does $A^TB=(B^TA)^T$ help? –  Jonas Meyer Jan 10 '13 at 4:32
That's it @ACARCHAU. Thanks to you both. Mind posting as an answer so I can accept and close the question? –  Clayton Stanley Jan 10 '13 at 4:35

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