NAME¶
cdawson, dawson - Dawson's integralSYNOPSIS¶
#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).
RESOURCES¶
Project web site: http://apps.jcns.fz-juelich.de/libcerfREFERENCES¶
The computation of D(z) is based on Faddeeva's function w_of_z; to compute D(x), the imaginary part im_w_of_x is used.BUG REPORTS¶
Please report bugs to the authors.AUTHORS¶
Steven G. Johnson [http://math.mit.edu/~stevenj], Massachusetts Institute of Technology, researched the numerics, and implemented the Faddeeva function.Joachim Wuttke <j.wuttke@fz-juelich.de>, Forschungszentrum Juelich, reorganized the code into a library, and wrote this man page.
