"WebYou had part b right, but you can't always multiply two matrices with the same dimensions. Take your example [1x3] * [1x3]. They are both 1x2 matrices. Since the the number of columns of the first matrix isn't equal to the number of rows of the second (2 and 1) this operation is undefined. :D Hope this helps! 2 comments ( 9 votes) Upvote Flag Arya " - Multiply is not defined
