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
var	stan::math::digamma (const var &a)
	Return the derivative of the log gamma function at the specified value.
template<typename T , require_var_matrix_t< T > * = nullptr>
auto	stan::math::digamma (const T &a)
	Return the elementwise derivative of the log gamma function at the given input vector.
