Synopsis
#include <flint/arb_fpwrap.h>int arb_fpwrap_double_gamma_upper(double * res, double s, double z, int regularized, int flags)sourceint arb_fpwrap_cdouble_gamma_upper(complex_double * res, complex_double s, complex_double z, int regularized, int flags)sourceCompute the upper incomplete gamma function \Gamma(s, z) (arb_hypgeom_gamma_upper, acb_hypgeom_gamma_upper); regularized selects the variants as in those functions (0: plain, 1: divided by \Gamma(s), 2: the generalised exponential integral normalisation).
