DILOG(3pm)
NAME
PDL::GSLSF::DILOG - 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_dilog
- Signature: (double x(); double [o]y(); double [o]e())
- /* Real part of DiLogarithm(x), for real argument. In Lewins notation, this is Li_2(x). Li_2(x) = - Re[ Integrate[ Log[1-s] / s, {s, 0, x}] ]
- gsl_sf_dilog 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_complex_dilog
- Signature: (double r(); double t(); double [o]re(); double [o]im(); double [o]ere(); double [o]eim())
- DiLogarithm(z), for complex argument z = r Exp[i theta].
- gsl_sf_complex_dilog does not process bad values. It will set the badvalue flag of all output piddles if the flag is set for any of the
input piddles.
