How to multiply a vector by a scalar
WebMultiplying a vector by a negative scalar reverses its direction, and scales its length by the magnitude of the scalar. It the magnitude of the scalar is greater than 1, then the new vector is longer than the original vector; if it is less than 1, then the new vector is shorter; if the scalar is equal to 1, the new vector has the same length as ... WebThe Multiply (A, B) function computes the product . The type of result that is returned depends on the type of A and B (see the table under Programming Note below). • The inplace option (ip) determines where the result is returned. If given as inplace=true, the result overwrites the first argument.
