function F = LR_sub(M,N)

% F=LR_sub(M,N)
%
% Subtraction of two fuzzy numbers/intervalls in LR representation.
% F,M,N = [Xmin Xmax m n alpha beta]
% mu_min=0, mu_max=1 and L=R.
% The substraction is a addition with sign reversal.
% M-N = M + (-N)
%
% F = [Xmin, Xmax, m1-n2, n1-m2, alpha1+beta2, beta1+alpha2]
