acb_hypgeom_bessel_k, acb_hypgeom_bessel_k_scaled
Synopsis
#include <flint/acb_hypgeom.h>Sets res to the modified Bessel function of the second kind K_\nu(z), or to e^z K_\nu(z), choosing between the asymptotic expansion and the convergent series. For real arguments with an inaccurate result they also try arb_hypgeom_bessel_k_integration.
