WebElementwise functions that take multiple arguments, such as maximum and multiply, operate on the corresponding elements of each argument. For example, if X and Y are both 3 by 3 matrix variables, then maximum (X, Y) is a 3 by 3 matrix expression. maximum (X, Y) [2, 0] is equivalent to maximum (X [2, 0], Y [2, 0]).
