Then multiply the elements of the individual row of the first matrix by the elements of all columns in the second matrix and add the products and arrange the added. Must be equal to the number of rows of the second matrix, otherwise it is impossible to multiply matrices.
I × a = a. Recall that the size of a matrix is the number of rows by the number of columns. As matrix multiplication (in component representation) is.
