noisegen - noise generation

### Calling Sequence

  `b=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` .

### Examples

    noisegen(0.5,30,1.0);
    x=-5:0.01:35;
    y=feval(x,Noise);
    plot(x,y);
