Functions

template<typename Ta , typename Tz , typename FvarT = return_type_t<Ta, Tz>, require_all_stan_scalar_t< Ta, Tz > * = nullptr, require_any_fvar_t< Ta, Tz > * = nullptr>
FvarT stan::math::hypergeometric_1f0 (const Ta &a, const Tz &z)
 Returns the Hypergeometric 1F0 function applied to the input arguments: \( _1F_0(a;;z) = \sum_{k=1}^{\infty}\frac{\left(a\right)_kz^k}{k!}\).
