kaiser

% error:  kaiser (n, beta)
%
% Returns the filter coefficients of the n-point Kaiser window with
% parameter beta.
%
% For the definition of the Kaiser window, see A. V. Oppenheim &
% R. W. Schafer, 'Discrete-Time Signal Processing'.
%
% The continuous version of width n centered about x=0 is:
%
%         besseli(0, beta * sqrt(1-(2*x/n).^2))
% k(x) =  -------------------------------------,  n/2 <= x <= n/2
%                besseli(0, beta)
