function [tfr,rtfr,hat] = tfrrspwv(x,t,N,g,h,trace); %TFRSPWV Reassigned smoothed pseudo Wigner-Ville distribution. % [TFR,RTFR,HAT] = TFRRSPWV(X,T,N,G,H,TRACE) % computes the smoothed pseudo Wigner-Ville distribution and its % reassigned version. % % X : analysed signal. % T : the time instant(s) (default : 1:length(X)). % N : number of frequency bins (default : length(X)). % G : time smoothing window, G(0) being forced to 1. % (default : Hamming(N/10)). % H : frequency smoothing window, H(0) being forced to 1 % (default : Hamming(N/4)). % TRACE : if nonzero, the progression of the algorithm is shown %
