cerf, cerfc - complex error functions
#include <cerf.h>
double _Complex cerf ( double _Complex z );
double _Complex cerfc ( double _Complex z );
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).

The computations are based on Faddeeva's function w_of_z.
Please report bugs to the authors.

researched the numerics, and implemented the Faddeeva function.

reorganized the code into a library, and wrote this man page.

The real error function comes with recent versions of glibc, as requested by the C99 standard:
