NAME

6       PDL::GSLSF::COULOMB - PDL interface to GSL Special Functions
7

DESCRIPTION

9       This is an interface to the Special Function package present in the GNU
10       Scientific Library.

SYNOPSIS

FUNCTIONS
14   gsl_sf_hydrogenicR
15         Signature: (double x(); double [o]y(); double [o]e(); int n; int l; double z)
16
17       Normalized Hydrogenic bound states. Radial dipendence.
18
19       gsl_sf_hydrogenicR does not process bad values.  It will set the bad-
20       value flag of all output ndarrays if the flag is set for any of the
21       input ndarrays.
22
23   gsl_sf_coulomb_wave_FGp_array
24         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)
25
26        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.
27
28       gsl_sf_coulomb_wave_FGp_array does not process bad values.  It will set
29       the bad-value flag of all output ndarrays if the flag is set for any of
30       the input ndarrays.
31
32   gsl_sf_coulomb_wave_sphF_array
33         Signature: (double x(); double [o]fc(n); int [o]ovfw(); double [o]fe(n); double lam_min; int kmax=>n; double eta)
34
35        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.
36
37       gsl_sf_coulomb_wave_sphF_array does not process bad values.  It will
38       set the bad-value flag of all output ndarrays if the flag is set for
39       any of the input ndarrays.
40
41   gsl_sf_coulomb_CL_e
42         Signature: (double L(); double eta();  double [o]y(); double [o]e())
43
44       Coulomb wave function normalization constant. [Abramowitz+Stegun
45       14.1.8, 14.1.9].
46
47       gsl_sf_coulomb_CL_e does not process bad values.  It will set the bad-
48       value flag of all output ndarrays if the flag is set for any of the
49       input ndarrays.
