Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.
namespace	stan::math
	Matrices and templated mathematical functions.

Functions
template<typename T , typename U >
T	stan::math::copysign (const T &x, const U &y)
	Return the negation of the first argument if the first and second argument have different signs, otherwise return a copy of the first argument.
template<typename T , typename U >
T	stan::math::copysign_non_zero (const T &x, const U &y)
	Return the negation of the first argument if the first and second arguments have different signs and the first argument is not zero, otherwise return a copy of the first argument.
template<typename T , typename U >
std::complex< T >	stan::math::copysign (const std::complex< T > &x, const std::complex< U > &y)
	Return the complex number composed of the real and complex parts with signs copied from the real and complex parts of the first arguments to the real and complex parts of the second.
