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 VecVar , require_std_vector_vt< is_var, VecVar > * = nullptr, typename... Pargs>
size_t	stan::math::internal::count_vars_impl (size_t count, VecVar &&x, Pargs &&... args)
	Count the number of vars in x (a std::vector of vars), add it to the running total, count the number of vars in the remaining arguments and return the result.
template<typename VecContainer , require_std_vector_st< is_var, VecContainer > * = nullptr, require_std_vector_vt< is_container, VecContainer > * = nullptr, typename... Pargs>
size_t	stan::math::internal::count_vars_impl (size_t count, VecContainer &&x, Pargs &&... args)
	Count the number of vars in x (a std::vector holding other containers), add it to the running total, count the number of vars in the remaining arguments and return the result.
template<typename EigT , require_eigen_vt< is_var, EigT > * = nullptr, typename... Pargs>
size_t	stan::math::internal::count_vars_impl (size_t count, EigT &&x, Pargs &&... args)
	Count the number of vars in x (an eigen container), add it to the running total, count the number of vars in the remaining arguments and return the result.
template<typename... Pargs>
size_t	stan::math::internal::count_vars_impl (size_t count, const var &x, Pargs &&... args)
	Add one to the running total number of vars, count the number of vars in the remaining arguments and return the result.
template<typename Arith , require_arithmetic_t< scalar_type_t< Arith > > * = nullptr, typename... Pargs>
size_t	stan::math::internal::count_vars_impl (size_t count, Arith &x, Pargs &&... args)
	Arguments without vars contribute zero to the total number of vars.
size_t	stan::math::internal::count_vars_impl (size_t count)
	End count_vars_impl recursion and return total number of counted vars.
template<typename... Pargs>
size_t	stan::math::count_vars (Pargs &&... args)
	Count the number of vars in the input argument list.
