NAME

6       cerfcx, erfcx - underflow-compensated complementary error function
7

SYNOPSIS

9       #include <cerf.h>
10
11       double _Complex cerfcx ( double _Complex z );
12
13       double          erfcx  ( double x );
14

DESCRIPTION

16       The function cerfcx is an underflow-compensated variant of the complex
17       error function: erfcx(z) = exp(z^2) erfc(z).
18
19       The function erfcx takes a real argument and returns a real result.
20

REFERENCES

22       The implementation of cerfcx is a thin wrapper around Faddeeva's
23       function w_of_z.
24
25       The implementation of erfcx is self-contained, and improves upon the
26       SLATEC DERFC function (or an erfcx function derived therefrom) or
27       Cody's CALERF function (from netlib.org/specfun), while retaining near
28       machine precision in accuracy.

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