			% AssociatedLaguerrePoly.m by David Terr, Raytheon, 5-11-04
			% Given nonnegative integers n and k with k<=n, compute the associated
			% Laguerre polynomial L{n,k}. Return the result as a vector whose mth
			% element is the coefficient of x^(n+1-m).
			% polyval(AssociatedLaguerrePoly(n,k),x) evaluates L{n,k}(x).
			% Note: This program requires downloading binomial.m first.
			function Lnk = AssociatedLaguerrePoly(n,k)
			if k==0
			Lnk = LaguerrePoly(n);
			else
			Lnk = zeros(n+1,1);

			for m=0:n
			Lnk(n+1-m) = (-1)^m * binomial(k+n,n-m) / factorial(m);
