function wind=lagwind(lag,window)

%	LAGWIND Lag window function
%
%	wind=lagwind(lag,window)
%
%	The lag element window vector is computed from the lag scalar and window function
%	string.  If unspecified, the lag scalar is entered after the prompt from the
%	keyboard.  The window string specifies lag window vector computation, according to:
%
%	window = 'uniform', 'u', or unspecified computes the uniform window
%	       = 'sasaki' or 's' computes the sasaki window
%	       = 'priestley' or 'p' computes the priestley window
%	       = 'parzen' or 'pa' computes the parzen window
%	       = 'hamming' or 'h' computes the hamming window
%	       = 'gaussian' or 'g' computes the gaussian distribution window
%	       = 'daniell' or 'd' computes the daniell window

%	Implemented using MATLAB 5.3.1
