function h=tftb_window(N,name,param,param2);%tftb_window	Window generation.%	H=tftb_window(N,NAME,PARAM,PARAM2)%	yields a window of length N with a given shape.%%	N      : length of the window%	NAME   : name of the window shape (default : Hamming)%	PARAM  : optional parameter%	PARAM2 : second optional parameters%%	Possible names are :%	'Hamming', 'Hanning', 'Nuttall',  'Papoulis', 'Harris',%	'Rect',    'Triang',  'Bartlett', 'BartHann', 'Blackman'%	'Gauss',   'Parzen',  'Kaiser',   'Dolph',    'Hanna'.%	'Nutbess', 'spline',  'Flattop'%%	For the gaussian window, an optionnal parameter K%	sets the value at both extremities. The default value is 0.005%%	For the Kaiser-Bessel window, an optionnal parameter%	sets the scale. The default value is 3*pi.%%	For the Spline windows, h=tftb_window(N,'spline',nfreq,p)%	yields a spline weighting function of order p and frequency%	bandwidth proportional to nfreq.%%       Example: %        h=tftb_window(256,'Gauss',0.005); %        plot(0:255, h); axis([0,255,-0.1,1.1]); grid%%	See also DWINDOW.%	F.
