signal if auto-SPWV, or [X1,X2] if cross-SPWV.
time instant(s) (default : 1:length(X)) .
number of frequency bins (default : length(X)).
time smoothing window, G(0) being forced to 1. default : Hamming(N/10)).
frequency smoothing window in the time-domain, H(0) being forced to 1 (default : Hamming(N/4)).
if nonzero, the progression of the algorithm is shown (default : 0).
if one input parameter is 'plot', tfrspwv runs tfrqview. and TFR will be plotted
time-frequency representation.
vector of normalized frequencies.
computes the Smoothed Pseudo Wigner-Ville distribution of a discrete-time signal X, or the cross Smoothed Pseudo Wigner-Ville representation between two signals.
