NAME

6       cdawson, dawson - Dawson's integral
7

SYNOPSIS

9       #include <cerf.h>
10
11       double _Complex cdawson ( double _Complex z );
12
13       double          dawson  ( double x );
14

DESCRIPTION

16       The function cdawson returns Dawson's integral D(z) = exp(-z^2)
17       integral from 0 to z exp(t^2) dt = sqrt(pi)/2  *  exp(-z^2) * erfi(z).
18
19       For function dawson takes a real argument x, and returns the real
20       result D(x).
21

SEE ALSO

23       The computation of D(z) is based on Faddeeva's function w_of_z(3); to
24       compute D(x), the imaginary part im_w_of_x(3) is used.
25
26       Other complex error functions: w_of_z(3), voigt(3), cerf(3), erfcx(3),
27       erfi(3).
