libcerf

Self-contained numeric library that provides an efficient and accurate implementation of complex error functions, along with Dawson, Faddeeva, and Voigt functions.

Functions:

• erf (complex)
• erfc (complex)
• erfcx (both)
• erfi (both)
• dawson (both)
• voigt
• fadeeva (complex)
• fadeevaIm (double)

Example:

import std.complex, std.math;
import libcerf;

auto c = erfi(complex(1.0, 0.0));
auto f = erfi(1.0);

assert(fabs((c.re - f)/f) < 1e-13);
