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 >
fvar< T >	stan::math::trigamma (const fvar< T > &u)
	Return the value of the trigamma function at the specified argument (i.e., the second derivative of the log Gamma function at the specified argument).
