| The Jacobian Elliptic functions are defined in Abramowitz & Stegun, |
| Chapter 16. The functions are declared in the header file |
| @file{gsl_sf_elljac.h}. |
| |
| @deftypefun int gsl_sf_elljac_e (double @var{u}, double @var{m}, double * @var{sn}, double * @var{cn}, double * @var{dn}) |
| This function computes the Jacobian elliptic functions @math{sn(u|m)}, |
| @math{cn(u|m)}, @math{dn(u|m)} by descending Landen |
| transformations. |
