function g = GL(x,pos,wid,m)
% Gaussian/Lorentzian blend.
% pos=position; wid=half-width;
% m = percent Gaussian character.
%  T. C. O'Haver, 2012
g=2*((m/100)*gaussian(x,pos,wid)+(1-(m/100))*lorentzian(x,pos,wid))/2;

function g = gaussian(x,pos,wid)
%  gaussian(x,pos,wid) = gaussian peak centered on pos, half-width=wid
%  x may be scalar, vector, or matrix, pos and wid both scalar
%  T. C. O'Haver, 1988
% Examples: gaussian([0 1 2],1,2) gives result [0.5000    1.0000    0.5000]
% plot(gaussian([1:100],50,20)) displays gaussian band centered at 50 with width 20.
g = exp(-((x-pos)./(0.60056120439323.*wid)) .^2);

function g = lorentzian(x,position,width)
% lorentzian(x,position,width) Lorentzian function.
% where x may be scalar, vector, or matrix
% position and width scalar
% T. C. O'Haver, 1988
% Example: lorentzian([1 2 3],2,2) gives result [0.5 1 0.5]
g=ones(size(x))./(1+((x-position)./(0.5.*width)).^2);
