atan2 function template — Computes inverse tangent of two arguments

Synopsis

template<typename T>
valarray<T> atan2(const valarray<T>& b, const valarray<T>& a);
template<typename T> valarray<T> atan2(const valarray<T>& b, const T& x);
template<typename T> valarray<T> atan2(const T& y, const valarray<T>& a);

The atan2 function computes the inverse tangent of y/x, in which y is a scalar or an element of b, and x is a scalar or an element of a.
