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

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 ndarrays if the flag is set for any of the input
21 ndarrays.
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 ndarrays if the flag is set for any of the input
30 ndarrays.
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 ndarrays if the flag is set for any of the input
39 ndarrays.
