WebTo multiply matrices they need to be in a certain order. If you had matrix 1 with dimensions axb and matrix 2 with cxd then it depends on what order you multiply them. Kind of like subtraction where 2-3 = -1 but 3-2=1, it changes the answer. So if you did matrix 1 times matrix 2 then b must equal c in dimensions. WebIt is a special matrix, because when we multiply by it, the original is unchanged: A × I = A. I × A = A. Order of Multiplication.
