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).

SEE ALSO

The computations are based on Faddeeva’s function w_of_z(3).
Other complex error functions in libcerf: w_of_z(3), dawson(3), voigt(3), erfcx(3), erfi(3).
The real error function comes with recent versions of glibc, as requested by the C99 standard: erf(3)
