function h=window(N,name,param,param2);%WINDOW	Window generation.%	H=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'%%	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=window(N,'spline',nfreq,p)%	yields a spline weighting function of order p and frequency%	bandwidth proportional to nfreq.%%	Example : h=window(256,'Gauss',0.005); plot(h);%%	See also DWINDOW.%	F.
