NAME

cerfi, erfi - imaginary error function

SYNOPSIS

#include <cerf.h >

double _Complex cerfi ( double _Complex z );

double erfi ( double x );

DESCRIPTION

The function cerfi returns an error function rotated in the complex plane, erfi(z) = -i erf(iz).

The function erfi takes a real argument and returns a real result.

SEE ALSO

The implementation of cerfi and erfi is trivially based on the functions cerf (3) and im_w_of_x (3).

Other complex error functions in libcerf: dawson (3), erfcx (3), voigt (3), w_of_z (3).

The real error function comes with recent versions of glibc, as requested by the C99 standard: erf (3).
