NAME
PDL::GSLSF::HYPERG - PDL interface to GSL Special Functions
DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library.
SYNOPSIS
Functions
FUNCTIONS
gsl_sf_hyperg_0F1
Signature: (double x(); double [o]y(); double [o]e(); double c)
/* Hypergeometric function related to Bessel functions 0F1[c,x] = Gamma[c] x^(1/2(1-c)) I_{c-1}(2 Sqrt[x]) Gamma[c] (-x)^(1/2(1-c))
J_{c-1}(2 Sqrt[-x])
gsl_sf_hyperg_1F1
Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
Confluent hypergeometric function for integer parameters. 1F1[a,b,x] = M(a,b,x)
gsl_sf_hyperg_U
Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
Confluent hypergeometric function for integer parameters. U(a,b,x)
gsl_sf_hyperg_2F1
Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
Confluent hypergeometric function for integer parameters. 2F1[a,b,c,x]
gsl_sf_hyperg_2F1_conj
Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
Gauss hypergeometric function 2F1[aR + I aI, aR - I aI, c, x]
gsl_sf_hyperg_2F1_renorm
Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
Renormalized Gauss hypergeometric function 2F1[a,b,c,x] / Gamma[c]
gsl_sf_hyperg_2F1_conj_renorm
Signature: (double x(); double [o]y(); double [o]e(); double a; double b; double c)
Renormalized Gauss hypergeometric function 2F1[aR + I aI, aR - I aI, c, x] / Gamma[c]
gsl_sf_hyperg_2F0
Signature: (double x(); double [o]y(); double [o]e(); double a; double b)
Mysterious hypergeometric function. The series representation is a divergent hypergeometric series. However, for x < 0 we have 2F0(a,b,x) =
(-1/x)^a U(a,1+a-b,-1/x)
