Homework Help: matrices

Posted by Yadlay on Tuesday, April 13, 2010 at 11:13pm.

Two matrices can be multiplied only if their sizes are compatible. Suppose that U is an m n matrix, and that V is a p q matrix. In order for UV to make sense, what must be true of the dimensions of these matrices? Although matrix multiplication uses dot products, it is common to write UV without the dot, which will be done from now on.
