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);
