NAME

6       PDL::GSLSF::ZETA - PDL interface to GSL Special Functions
7

DESCRIPTION

9       This is an interface to the Special Function package present in the GNU
10       Scientific Library.
11

SYNOPSIS

FUNCTIONS

14   gsl_sf_zeta
15         Signature: (double x(); double [o]y(); double [o]e())
16
17       Riemann Zeta Function zeta(x) = Sum[ k^(-s), {k,1,Infinity} ], s != 1.0
18
19       gsl_sf_zeta does not process bad values.  It will set the bad-value
20       flag of all output piddles if the flag is set for any of the input
21       piddles.
22
23   gsl_sf_hzeta
24         Signature: (double s(); double [o]y(); double [o]e(); double q)
25
26       Hurwicz Zeta Function zeta(s,q) = Sum[ (k+q)^(-s), {k,0,Infinity} ]
27
28       gsl_sf_hzeta does not process bad values.  It will set the bad-value
29       flag of all output piddles if the flag is set for any of the input
30       piddles.
31
32   gsl_sf_eta
33         Signature: (double x(); double [o]y(); double [o]e())
34
35       Eta Function eta(s) = (1-2^(1-s)) zeta(s)
36
37       gsl_sf_eta does not process bad values.  It will set the bad-value flag
38       of all output piddles if the flag is set for any of the input piddles.
