NAME
cerfcx, erfcx - underflow-compensated complementary error functionSYNOPSIS
#include <cerf.h> double _Complex cerfcx ( double _Complex z ); double erfcx ( double x );DESCRIPTION
The function cerfcx is an underflow-compensated variant of the complex error function: erfcx(z) = exp(z^2) erfc(z). The function erfcx takes a real argument and returns a real result.RESOURCES
Project web site: http://apps.jcns.fz-juelich.de/libcerfREFERENCES
The implementation of cerfcx is a thin wrapper around Faddeeva's function w_of_z. The implementation of ercx is self-contained, and improves upon the SLATEC DERFC function (or an erfcx function derived therefrom) or Cody's CALERF function (from netlib.org/specfun), while retaining near machine precision in accuracy.BUG REPORTS
Please report bugs to the authors.AUTHORS
Steven G. Johnson [http://math.mit.edu/~stevenj],Massachusetts Institute of Technology,
researched the numerics, and implemented the Faddeeva function. Joachim Wuttke <[email protected]>, Forschungszentrum Juelich,
reorganized the code into a library, and wrote this man page.
