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);
