Synopsis#include <flint/arb_hypgeom.h>
void arb_hypgeom_bessel_i_integration(arb_t res, const arb_t nu, const arb_t z, int scaled, slong prec)source
void arb_hypgeom_bessel_k_integration(arb_t res, const arb_t nu, const arb_t z, int scaled, slong prec)source

Computes I_\nu(z) or K_\nu(z) (multiplied by e^{-z} or e^{z} if scaled is nonzero) by rigorous numerical integration of an integral representation. These functions are intended for large \nu, where the series expansions are slow; acb_hypgeom_bessel_i and acb_hypgeom_bessel_k use them as fallbacks for real arguments.
