y = sinedamp(p, x, [y]) : Sine function.


function y=sinedamp(varargin)


 y = sinedamp(p, x, [y]) : Sine function. 

   iFunc/sinedamp Damped Sine function. 
     y  = p(4) + p(1)*sin((x - p(2))/p(3)).*exp(-x/p(5))

 sinedamp(period)         creates a model with specified period
 sinedamp([ parameters ]) creates a model with specified model parameters

 input:  p: Sine model parameters (double)
            p = [ Amplitude Phase_Shift Period BackGround Decay ]
          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=sinedamp([1 0 1 1], -10:10); or plot(sinedamp);
