**Matrix Multiplication / The Identity Matrix**

26/02/2012 · Best Answer: If the order is (3x1) times (1x3), then the result is 3x3. If the order is (1x3) times (3x1), then the result is 1x1. So in matrix multiplication, the order matters.... 17/07/2003 · Date: 07/16/2003 at 23:11:39 From: Doctor Peterson Subject: Re: Multiplying Matrices and Identifying Dimensionality Hi, Rick. Your second example is a 3x1 times a 1x3, so the inner dimensions ARE the same (both 1), and they CAN be multiplied.

23/03/2008 · The second matrix should be a 3x1 vertical matrix (rather than a 1x3 horizontal matrix). If they are both 1x3 horizontal matrices, you can't multiply them If they are both 1x3 horizontal matrices, you can't multiply them... Multiplying by the identity. Multiplying by the identity matrix I doesn't change anything, just like multiplying a number by 1 doesn't change anything.
