operator+ function template — Performs addition
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 addition. It adds 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 adding two arrays, they must have
the same size. The resulting array has the same size as the argument
array(s).
