iFit/green

PURPOSE ^

y = green(p, x, [y]) : Green function

SYNOPSIS ^

function y=green(varargin)

DESCRIPTION ^

 y = green(p, x, [y]) : Green function

   iFunc/green Green fitting function
     y = (p(1)*p(3)*p(2)^2 ) ./ ( (p(2)^2 - x.^2).^2 + (x*p(3)).^2) + p(4);

 green(energy)         creates a model with a line at specified energy (centre)
 green([ parameters ]) creates a model with specified model parameters

 input:  p: Green model parameters (double)
            p = [ Amplitude Center HalfWidth BackGround ]
          or 'guess'
         x: axis (double)
         y: when values are given and p='guess', a guess of the parameters is performed (double)
 output: y: model value
 ex:     y=green([1 0 1 1], -10:10); or plot(green);
