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.
namespace	stan::math::internal
	A comparator that works for any container type that has the brackets operator.

Functions
template<typename T >
void	stan::math::internal::sum_to_zero_vector_backprop (T &&y_adj, const Eigen::VectorXd &z_adj)
	The reverse pass backprop for the sum_to_zero_constrain on vectors.
template<typename T , require_rev_col_vector_t< T > * = nullptr>
auto	stan::math::sum_to_zero_constrain (T &&y)
	Return a vector with sum zero corresponding to the specified free vector.
template<typename T , require_rev_matrix_t< T > * = nullptr, require_not_t< is_rev_vector< T > > * = nullptr>
auto	stan::math::sum_to_zero_constrain (T &&x)
	Return a matrix that sums to zero over both the rows and columns corresponding to the free matrix x.
template<typename T , typename Lp , is_rev_matrix< T > * = nullptr>
auto	stan::math::sum_to_zero_constrain (T &&y, Lp &lp)
	Return a vector with sum zero corresponding to the specified free vector.
