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 bad-value flag of all output piddles
       if the flag is set for any of the input piddles.
