WebYou can multiply a 2x 3 matrix times a 3 x1 matrix but you can not multiply a 3x 1 matrix times a 2 x3 matrix. The dimension of the matrix resulting from a matrix multiplication is the first dimension of the first matrix by the last dimenson of the second matrix. Multiplying a 2 x3 matrix times a 3x 1 matrix yields a 2 x 1 matrix. WebIn fact, we do not need to have two matrices of the same size to multiply them. Above, we did multiply a (2x2) matrix with a (2x1) matrix (which gave a (2x1) matrix). In fact, the general rule says that in order to perform the multiplication AB, where A is a (mxn) matrix and B a (kxl) matrix, then we must have n = k.
