=head1 NAME
PDL::GSLSF::DILOG - PDL interface to GSL Special Functions
=head1 DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library.
=head1 SYNOPSIS
=cut
=head1 FUNCTIONS
=cut
=head2 gsl_sf_dilog
=for sig
Signature: (double x(); double [o]y(); double [o]e())
=for ref
/* 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}] ]
=for bad
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.
=cut
*gsl_sf_dilog = \&PDL::gsl_sf_dilog;
=head2 gsl_sf_complex_dilog
=for sig
Signature: (double r(); double t(); double [o]re(); double [o]im(); double [o]ere(); double [o]eim())
=for ref
DiLogarithm(z), for complex argument z = r Exp[i theta].
=for bad
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.
