y = voigt(p, x, [y]) : Voigt function
iFunc/voigt Voigt fitting function, including Bose factor.
The Width parameters of the Gaussian and Lorentzian are the Half Widths.
voigt(width) creates a model with a specified width
voigt([ parameters ]) creates a model with specified model parameters
Reference: http://en.wikipedia.org/wiki/Voigt_profile
input: p: Voigt model parameters (double)
p = [ Amplitude Centre Width_Gauss Width_Lorz 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=voigt([1 0 1 1], -10:10); or plot(voigt);
