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

       Riemann Zeta Function zeta(x) = Sum[ k^(-s), {k,1,Infinity} ], s != 1.0

       gsl_sf_zeta 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_hzeta
	 Signature: (double s(); double [o]y(); double [o]e(); double q)

       Hurwicz Zeta Function zeta(s,q) = Sum[ (k+q)^(-s), {k,0,Infinity} ]

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

       Eta Function eta(s) = (1-2^(1-s)) zeta(s)

       gsl_sf_eta 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.
