Reassigned Gabor spectrogram time-frequency distribution.
[TFR,RTFR,HAT] = tfrrgab(X) [TFR,RTFR,HAT] = tfrrgab(X,T) [TFR,RTFR,HAT] = tfrrgab(X,T,N) [TFR,RTFR,HAT] = tfrrgab(X,T,N,NH) [TFR,RTFR,HAT] = tfrrgab(X,T,N,NH,TRACE) [TFR,RTFR,HAT] = tfrrgab(X,T,N,NH,TRACE,K) [TFR,RTFR,HAT] = tfrrgab(...,'plot')
analysed signal
the time instant(s) (default : 1:length(X))
number of frequency bins (default : length(X))
length of the gaussian window (default : N/4))
if nonzero, the progression of the algorithm is shown (default : 0).
value at both extremities (default 0.001)
if one input parameter is 'plot', tfrrgab runs tfrqview. and TFR will be plotted
time-frequency representation and its reassigned
Complex matrix of the reassignment vectors.
tfrrgab computes the Gabor spectrogram and its reassigned version. This particular window (a Gaussian window) allows a 20 % faster algorithm than the tfrrsp function.
