signal.
frequency smoothing windows, the H(:,i) being normalized so as to be of unit energy.
time instant(s) (default : 1:length(X)).
number of frequency bins (default : length(X))
if nonzero, the progression of the algorithm is shown (default : 0).
if one input parameter is 'plot', tfrmh runs tfrqview. and TFR will be plotted
time-frequency representation.
vector of normalized frequencies.
tfrmmce computes the minimum mean cross-entropy combination of spectrograms using as windows the columns of the matrix H.
