Frequency moments of a time-frequency representation.
[TM,D2]=momftfr(TFR) [TM,D2]=momftfr(TFR,TMIN) [TM,D2]=momftfr(TFR,TMIN,TMAX) [TM,D2]=momftfr(TFR,TMIN,TMAX,TIME)
time-frequency representation ([Nrow,Ncol]size(TFR)).
smallest column element of TFR taken into account (default : 1)
highest column element of TFR taken into account (default : Ncol)
true time instants (default : 1:Ncol)
averaged time (first order moment)
squared time duration (second order moment)
momftfr computes the frequeny moments of a time-frequency representation.
