Matrix multiplication is more complex than matrix addition or subtraction, and is carried out in accordance with a strict rule that stems directly from the fact that the technique was developed to facilitate solution of systems of linear equations. If C is a matrix resulting from the multiplication of two matrices, A and B, then the elements ...

The same is true of matrix addition and subtraction, but – and this has important ramifications for your work with Matlab – matrix multiplication is generally not commutative: that is, if A and B are two matrices, in general . The significance of this is that the ordering of matrices is important when you’re setting up the calculation of ...
