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. WebMatrices are considered equal if they have the same dimensions and if each element of one matrix is equal to the corresponding element of the other matrix. You may multiply a …
