test_mode_1.m

用matlab实现了五类灰色关联度模型的计算

% test_mode_1
% 0<delta<1, n=1000;
function [x,y,z]=test_mode_1(delta,n)
x(1) = 0.5;
y(1) = 2;
z(1) = -0.1;
for i = 1 : n
  %   delta=rand();
    x(i+1) = 0.8*x(i) - 2.7*y(i);
    y(i+1) = (1 - delta)*(1 - 0.2*y(i)) + delta*(1 + 0.8*x(i));
    z(i+1) = 0.3*z(i) - 1.2*y(i);
end
