时间序列的时频分析工具箱

function tfrparam(method);
%TFRPARAM Return the paramaters needed to display (or save) this TFR.
%	TFRPARAM(METHOD) returns on the screen the meaning of the
%	parameters P1..P5 used in the files TFRQVIEW, TFRVIEW and TFRSAVE,
%	to view or save a time-frequency representation.
%
%	METHOD : chosen representation (name of the corresponding M-file).   
%
%	Example : 
%	 tfrparam('tfrspwv');
%
%	See also TFRQVIEW, TFRVIEW, TFRPARAM.
