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.
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 ndarrays if the flag is set for any of the input ndarrays.
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 ndarrays if the flag is set for any of the input ndarrays.
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 ndarrays if the flag is set for any of the input ndarrays.
