function [tfrtf] = tfrwv(xtNtrace);
%TFRWV Wigner-Ville time-frequency distribution.
% [TFRTF]=TFRWV(XTNTRACE) computes the Wigner-Ville distribution
% of a discrete-time signal X
% or the cross Wigner-Ville representation between two signals.
%
% X : signal if auto-WV or [X1X2] if cross-WV.
% T : time instant(s) (default : 1:length(X)).
% N : number of frequency bins (default : length(X)).
% TRACE : if nonzero the progression of the algorithm is shown
% (default : 0).
% TFR : time-frequency representation. When called without
% output arguments TFRWV runs TFRQVIEW.
% F : vector of normalized frequencies.
%
% Example :
% sig=fmlin(1280.10.4); tfrwv(sig);
%
% See also all the time-frequency representations listed in
% the file CONTENTS (TFR*)
