Synopsis
#include <flint/arb_fpwrap.h>int arb_fpwrap_double_jacobi_p(double * res, double n, double a, double b, double x, int flags)sourceint arb_fpwrap_cdouble_jacobi_p(complex_double * res, complex_double n, complex_double a, complex_double b, complex_double x, int flags)sourceCompute the Jacobi function P_n^{(a,b)}(x) (arb_hypgeom_jacobi_p, acb_hypgeom_jacobi_p). In FLINT 3.6 and earlier the real version computed P_n^{(a,x)}(0) instead; the complex version was correct.
