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