d2statio

Distance to stationarity

Calling Sequence

[D,F] = D2STATIO(SIG)

Parameters

SIG :

signal to be analyzed (real or complex).

D :

vector giving the distance to stationarity for each frequency.

F :

vector of frequency bins

Description

d2statio evaluates the distance of the signal to stationarity, using the pseudo Wigner-Ville distribution.

Examples

rand("seed",0);
sig = noisecg(128); 
[d,f] = d2statio(sig);
clf
subplot(211); plot(f,d);
xlabel(_('Frequency')); ylabel(_('Distance'));

sig = fmconst(128); 
[d,f] = d2statio(sig);
subplot(212);plot(f,d);
xlabel(_('Frequency')); ylabel(_('Distance'));
