grad_2F1() [2/2]

template<typename T1 , typename T2 , typename T3 , typename T_z >

auto stan::math::grad_2F1 ( const T1 &  a1, const T2 &  a2, const T3 &  b1, const T_z &  z, double  precision = 1e-14, int  max_steps = 1e6  )

inline

Calculate the gradients of the hypergeometric function (2F1) as the power series stopping when the series converges to within precision or throwing when the function takes max_steps steps.

Template Parameters

T1	scalar type of a1
T2	scalar type of a2
T3	scalar type of b1
T_z	scalar type of z

Parameters

[in]	a1	see generalized hypergeometric function definition
[in]	a2	see generalized hypergeometric function definition
[in]	b1	see generalized hypergeometric function definition
[in]	z	see generalized hypergeometric function definition
[in]	precision	magnitude of the increment of the infinite sum to truncate the sum
[in]	max_steps	number of steps to take
