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 , require_not_tuple_t< T > * = nullptr>
ref_type_t< T && >	stan::math::to_ref (T &&a)
	This evaluates expensive Eigen expressions.
template<typename T , require_tuple_t< T > * = nullptr>
auto	stan::math::to_ref (T &&a)
	Overload that handles tuples.
template<bool Cond, typename T , std::enable_if_t<!Cond > * = nullptr>
T	stan::math::to_ref_if (T &&a)
	No-op that should be optimized away.
template<bool Cond, typename T , std::enable_if_t< Cond > * = nullptr>
ref_type_t< T && >	stan::math::to_ref_if (T &&a)
	If the condition is true, evaluates expensive Eigen expressions.
