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 T1 , typename T2 , require_all_not_st_var< T1, T2 > * = nullptr, require_all_stan_scalar_t< T1, T2 > * = nullptr>
return_type_t< T1, T2 >	stan::math::log_sum_exp (const T2 &a, const T1 &b)
	Calculates the log sum of exponentials without overflow.
template<typename T , require_container_st< is_fvar, T > * = nullptr>
auto	stan::math::log_sum_exp (const T &x)
	Return the log of the sum of the exponentiated values of the specified matrix of values.
template<typename T1 , typename T2 , require_any_container_t< T1, T2 > * = nullptr>
auto	stan::math::log_sum_exp (const T1 &a, const T2 &b)
	Enables the vectorized application of the log_sum_exp function, when the first and/or second arguments are containers.
