NAME¶

cerf, cerfc - complex error functions

SYNOPSIS¶

#include <cerf.h> double _Complex cerf ( double _Complex z ); double _Complex cerfc ( double _Complex z );

DESCRIPTION¶

The function cerf is the complex version of the error function: erf(z) = 2/sqrt(pi) * integral from 0 to z of exp(-t*t) dt. The complementary complex error function cerfc is defined as erfc(z) = 1-cerf(z).

REFERENCES¶

The computations are based on Faddeeva's function w_of_z.

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.
