Classes
struct	stan::math::tgamma_fun
	Structure to wrap tgamma() so that it can be vectorized. More...

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
double	stan::math::tgamma (double x)
	Return the gamma function applied to the specified argument.
template<typename T , require_all_not_nonscalar_prim_or_rev_kernel_expression_t< T > * = nullptr, require_not_var_matrix_t< T > * = nullptr>
auto	stan::math::tgamma (const T &x)
	Vectorized version of tgamma().
