NAME
       voigt_hwhm - Half width at half maximum of Voigt's function

SYNOPSIS
       #include <cerf.h>

       double voigt_hwhm ( double sigma, double gamma );

DESCRIPTION
       The function voigt_hwhm returns the half width at half maximum of the
       function voigt.

       The function voigt returns Voigt's convolution

         voigt(x,sigma,gamma) = integral G(t,sigma) L(x-t,gamma) dt

       of a Gaussian

         G(x,sigma) = 1/sqrt(2*pi)/|sigma| * exp(-x^2/2/sigma^2)

       and a Lorentzian

         L(x,gamma) = |gamma| / pi / ( x^2 + gamma^2 ),

       with the integral extending from -infinity to +infinity.
