PDL::GSLSF::COULOMB - PDL interface to GSL Special Functions This is an interface to the Special Function package present in the GNU Scientific Library.

gsl_sf_hydrogenicR
Signature: (double x(); double [o]y(); double [o]e(); int n; int l; double z) Normalized Hydrogenic bound states. Radial dipendence.

gsl_sf_coulomb_wave_FGp_array
Signature: (double x(); double [o]fc(n); double [o]fcp(n); double [o]gc(n); double [o]gcp(n); int [o]ovfw(); double [o]fe(n); double [o]ge(n); double lam_min; int kmax=>n; double eta) Coulomb wave functions F_{lam_F}(eta,x), G_{lam_G}(eta,x) and their derivatives; lam_G := lam_F - k_lam_G. if ovfw is signaled then F_L(eta,x) = fc[k_L] * exp(fe) and similar.

gsl_sf_coulomb_wave_sphF_array
Signature: (double x(); double [o]fc(n); int [o]ovfw(); double [o]fe(n); double lam_min; int kmax=>n; double eta) Coulomb wave function divided by the argument, F(xi, eta)/xi. This is the function which reduces to spherical Bessel functions in the limit eta->0.

gsl_sf_coulomb_CL
Signature: (double L(); double eta(); double [o]y(); double [o]e()) Coulomb wave function normalization constant. [Abramowitz+Stegun 14.1.8, 14.1.9].
