NAME
       PDL::GSLSF::ERF - 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_erfc
	 Signature: (double x(); double [o]y(); double [o]e())

       Complementary Error Function erfc(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2],
       {t,x,Infinity}]

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

       Log Complementary Error Function

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

       Error Function erf(x) := 2/Sqrt[Pi] Integrate[Exp[-t^2], {t,0,x}]

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

       Z(x) :  Abramowitz+Stegun 26.2.1

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

       Q(x) :  Abramowitz+Stegun 26.2.1

       gsl_sf_erf_Q 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.
