wrkdirs::usr...::man::dawson(3)	libcerf	manual wrkdirs::usr...::man::dawson(3)

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).
