y = pareto(p, x, [y]) : Pareto distribution function.
iFunc/pareto Pareto distribution function.
y = p(4)+ p(1)*(p(3)./x).^p(2);
pareto(width) creates a model with a specified width
pareto([ parameters ]) creates a model with specified model parameters
Reference: http://en.wikipedia.org/wiki/Pareto_distribution
input: p: Pareto model parameters (double)
p = [ Amplitude Exponent Width 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=pareto([1 0 1 1], -10:10); or plot(pareto);
