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

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_0F1 does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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_1F1 does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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_U does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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 does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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_conj does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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_renorm does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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_2F1_conj_renorm does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

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)

gsl_sf_hyperg_2F0 does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
