Spectrogram time-frequency distribution.
[TFR,T,F]=tfrsp(X) [TFR,T,F]=tfrsp(X,T) [TFR,T,F]=tfrsp(X,T,N) [TFR,T,F]=tfrsp(X,T,N,H) [TFR,T,F]=tfrsp(X,T,N,H,TRACE) [TFR,T,F]=tfrsp(...,'plot')
tfrsp computes the Spectrogram distribution of a discrete-time signal X.
signal.
time instant(s) (default : 1:length(X)).
number of frequency bins (default : length(X)).
analysis window, H being normalized so as to be of unit energy. (default : Hamming(N/4)).
if nonzero, the progression of the algorithm is shown (default : 0).
if one input parameter is 'plot', tfrsp runs tfrqview. and TFR will be plotted
time-frequency representation.
vector of normalized frequencies.
