noisegen
noise generation (obsolete)
Syntax
b = noisegen(pas, Tmax, sig)
Arguments
- pas
real scalar, the time increment
- Tmax
real scalar, the final time of the interval of noise generation
- sig
real scalar, the standard deviation of the noise
Description
noisegen() is obsolete. It will be removed from Scilab 6.1.x.
Please use grand() instead. Examples (clearer, shorter, and more powerful) follow:
100 10-point wide steps with random amplitudes of normal distribution of mean 1 and standard deviation 0.7: 40 15-point wide steps with random amplitudes of uniform distribution in [1 3], with initial level 0.5 and final level hold: |
noisegen()
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
Example #1: noisegen()
Example #2: rand()
