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(-zˆ2) integral from 0 to z exp(tˆ2) dt = sqrt(pi)/2 * exp(-zˆ2) * 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).
