WebActually, repeated addition of a matrix would be called scalar multiplication. For example, adding a matrix to itself 5 times would be the same as multiplying each element by 5. On the other hand, multiplying one matrix by another matrix is not the same as simply multiplying the corresponding elements. Check out the video on matrix multiplication. WebThe rule I've been following is this: the dimensions of the matrix are 2x1 and 2x2. The matrix cannot be multiplied if the inside two number (1 for the left column and 2 for the right column) are not the same, because the sizes of the two matrices being multiplied must be m x n and n x p .
