signal if auto-GRD, or [X1,X2] if cross-GRD.
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, H(0) being forced to 1. (default : Hamming(N/4)).
kernel width (default : 1).
dissymmetry ratio (default : 1).
if nonzero, the progression of the algorithm is shown (default : 0).
if one input parameter is 'plot', tfrgrd runs tfrqview. and TFR will be plotted
time-frequency representation.
vector of normalized frequencies.
tfrgrd computes the Generalized Rectangular distribution of a discrete-time signal X, or the cross GRD representation between two signals.
