void arb_hypgeom_bessel_k(arb_t res, const arb_t nu, const arb_t z, slong prec)source
void arb_hypgeom_bessel_k_scaled(arb_t res, const arb_t nu, const arb_t z, slong prec)source

Sets res to the modified Bessel function of the second kind K_\nu(z), or to the scaled function e^z K_\nu(z), which does not underflow for large z. Wrappers of acb_hypgeom_bessel_k and acb_hypgeom_bessel_k_scaled.
