7.13.3 Legendre Form of Complete Elliptic IntegralsFunction: *double*
*gsl_sf_ellint_Kcomp* *(double k, gsl_mode_t mode)*Function: *int*
*gsl_sf_ellint_Kcomp_e* *(double k, gsl_mode_t mode, gsl_sf_result
* result)*

These routines compute the complete elliptic integral *K(k)* to the
accuracy specified by the mode variable mode. Note that Abramowitz & Stegun
define this function in terms of the parameter *m = k^2*.
Function: *double* *gsl_sf_ellint_Ecomp* *(double k, gsl_mode_t mode)*
Function: *int* *gsl_sf_ellint_Ecomp_e* *(double k, gsl_mode_t mode,
gsl_sf_result * result)*

Yes, that is where I got a pointer to GSL. THere are 5 other open source
