NAME
       cdawson, dawson - Dawson's integral

SYNOPSIS
       #include <cerf.h>

       double _Complex cdawson ( double _Complex z );

       double          dawson  ( double x );

DESCRIPTION
       The function cdawson returns Dawson's integral D(z) = exp(-z^2)
       integral from 0 to z exp(t^2) dt = sqrt(pi)/2  *  exp(-z^2) * erfi(z).

       For function dawson takes a real argument x, and returns the real
       result D(x).

SEE ALSO
       The computation of D(z) is based on Faddeeva's function w_of_z(3); to
       compute D(x), the imaginary part im_w_of_x(3) is used.

       Other complex error functions: w_of_z(3), voigt(3), cerf(3), erfcx(3),
       erfi(3).
