build::libcerf::src::libcerf::man::cerf(3) libcerf manual NAME cerf, cerfc - complex error functions SYNOPSIS #include 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) Homepage: http://apps.jcns.fz-juelich.de/libcerf AUTHORS Steven G. Johnson, http://math.mit.edu/~stevenj, Massachusetts Institute of Technology, researched the numerics, and implemented the Faddeeva function. Joachim Wuttke , Forschungszentrum Juelich, reorganized the code into a library, and wrote this man page. Please report bugs to the authors.
