operator* function template — Performs multiplication
template<typename T> valarray<T> operator*(const valarray<T>& a, const valarray<T>& b); template<typename T> valarray<T> operator*(const valarray<T>& a, const T& y); template<typename T> valarray<T> operator*(const T& x, const valarray<T>& b);
The *
operator performs
elementwise multiplication. It multiplies each x
*
y
, in which x
is a scalar or an element of a
, and y
is a scalar or an element of b
. When multiplying two arrays, they must
have the same size. The resulting array has the same size as the
argument array(s).
