Synopsis#include <flint/gr_special.h>
int gr_bessel_i_scaled(gr_ptr res, gr_srcptr x, gr_srcptr y, gr_ctx_t ctx)source
int gr_bessel_k_scaled(gr_ptr res, gr_srcptr x, gr_srcptr y, gr_ctx_t ctx)source

Set res to the scaled Bessel functions e^{-z} I_\nu(z) and e^{z} K_\nu(z), which do not overflow for large z.
