gbruit            Scilab Group            Scilab Function            gbruit
NAME
   noisegen - noise generation 
  
CALLING SEQUENCE
 []=noisegen(pas,Tmax,sig)
DESCRIPTION
   generates a Scilab function [b]=Noise(t) where Noise(t) is a piecewise
  constant function  ( constant on  [k*pas,(k+1)*pas] ). The value on each
  constant  interval are random values from  i.i.d  Gaussian variables of 
  standard deviation sig. The function is constant for t<=0 and  t>=Tmax.
  
EXAMPLE
 noisegen(0.5,30,1.0);
 x=-5:0.01:35;
 y=feval(x,Noise);
 plot(x,y);
