=head1 FUNCTIONS

=cut





=head2 gsl_sf_expint_E1

=for sig

  Signature: (double x(); double [o]y(); double [o]e())

=for ref

E_1(x) := Re[ Integrate[ Exp[-xt]/t, {t,1,Infinity}] ]

=for bad

gsl_sf_expint_E1 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.
