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.

FUNCTIONS

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