Analyzed signal.
time instant(s) (default : 1:length(X)).
number of frequency bins (default : length(X)).
time smoothing window, (default : Hamming(N/10)).
frequency smoothing window, in the time-domain, (default : Hamming(N/4)).
kernel width
time-frequency representation.
vector of normalized frequencies.
