NAME

       PDL::GSLSF::FERMI_DIRAC - PDL interface to GSL Special Functions

DESCRIPTION

       This is an interface to the Special Function package present in the GNU Scientific Library.  Please note that:

       Complete Fermi-Dirac Integrals:

	F_j(x)	 := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,0,Infinity}]

       Incomplete Fermi-Dirac Integrals:

	F_j(x,b) := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,b,Infinity}]

SYNOPSIS

Functions
FUNCTIONS

       gsl_sf_fermi_dirac_int

	 Signature: (double x(); double [o]y(); double [o]e(); int j)

       Complete integral F_j(x) for integer j

       gsl_sf_fermi_dirac_mhalf

	 Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{-1/2}(x)

       gsl_sf_fermi_dirac_half

	 Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{1/2}(x)

       gsl_sf_fermi_dirac_3half

	 Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{3/2}(x)

       gsl_sf_fermi_dirac_inc_0

	 Signature: (double x(); double [o]y(); double [o]e(); double b)

       Incomplete integral F_0(x,b) = ln(1 + e^(b-x)) - (b-x)
