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 func-
     tion 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.
