Tent混沌映射

Tent混沌映射

代码实现

clc;clear all;close all
axis([0,1,0,1]);
x0=0.1;t=800;M=850;
r=0:0.002:1;
[m,n]=size(r);
hold on
for i=1:n
    if x0<0.5
        x(1)=2*r(i)*x0;
    end
    
    if x0>=0.5
        x(1)=2*r(i)*(1-x0);
    end
for j =2:M
     if x(j-1)<0.5
        x(j)=2*r(i)*x(j-1);
    end
    
    if x(j-1)>=0.5
        x(j)=2*r(i)*(1-x(j-1));
    end
end
xn{
    
    i}=x;
pause(0.1);
plot(r(i),xn{
    
    i},'b.','Markersize',2);
xlabel('r');ylabel('x(i)');
end
