@cindex Dawson function

The Dawson integral is defined by @math{\exp(-x^2) \int_0^x dt
\exp(t^2)}.  A table of Dawson's integral can be found in Abramowitz &
Stegun, Table 7.5.  The Dawson functions are declared in the header file
@file{gsl_sf_dawson.h}.

@deftypefun double gsl_sf_dawson (double @var{x})
@deftypefunx int gsl_sf_dawson_e (double @var{x}, gsl_sf_result * @var{result})
These routines compute the value of Dawson's integral for @var{x}.
