If at least one input is scalar then AB is equivalent to AB and is commutative.
How to multiply columns of a matrix in matlab. Size m 1 number of rows size m 2 number of columns. Once again google and the Matlab documentation are your friend. Learn more about matrix variable times.
A simple loop could do this for you too if you dont know the size of the matrix in hand. So I type in make matrix x 1 2 3 4 5 6 and y 7 7. Matrix multiplication is not universally commutative for nonscalar inputs.
That is AB is typically not equal to BA. I want to get a 1x6 or 6x1 matrix with results. You can simply use the inbuilt prod function as prod A2 or prod A.
