Synopsis
#include <flint/acb_hypgeom.h>void acb_hypgeom_jacobi_p(acb_t res, const acb_t n, const acb_t a, const acb_t b, const acb_t z, slong prec)sourceSets res to the Jacobi polynomial (or Jacobi function)
P_n^{(a,b)}(z) = \frac{(a+1)_n}{\Gamma(n+1)}\,
{}_2F_1\left(-n,n+a+b+1,a+1,\frac{1-z}{2}\right).
For nonnegative integer n this is a polynomial in a, b and z, also for parameters where the hypergeometric series is undefined; it is then evaluated by direct methods.
