y = pareto(p, x, [y]) : Pareto distribution function.


function y=pareto(varargin)


 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);
