function tfrsave(name,tfr,method,sig,t,f,p1,p2,p3,p4,p5);
%TFRSAVE Save the parameters of a time-frequency representation.
%	TFRSAVE(NAME,TFR,METHOD,SIG,T,F,P1,P2,P3,P4,P5) saves the 
%	parameters of a time-frequency representation in the file
%	NAME.mat. Two additional parameters are saved : TfrQView and
%	TfrView. If you load the file 'name.mat' and do eval(TfrQView), you
%	will restart the display session under tfrqview ; if you do
%	eval(TfrView), you will display the representation by means of
%	tfrview. 
% 
%	NAME   : name of the mat-file (less than 8 characters).   
%	TFR    : time-frequency representation (MxN).
%	METHOD : chosen representation.	
%	SIG    : signal from which the TFR was obtained 
%	T      : time instant(s)	   (default : (1:N)).
%	F      : frequency bins		   (default : linspace(0,0.5,M)).
%	P1..P5 : optional parameters : run the file TFRPARAM(METHOD) 
%		 to know the meaning of P1..P5 for your method.  
%
%	Example : 
%	 sig=fmlin(64); tfr=tfrwv(sig);
%	 tfrsave('wigner',tfr,'TFRWV',sig,1:64);  
%	 clear; load wigner; eval(TfrQView);
%
