Plotting bifurcation diagram
Posted:

Hi,
I am plotting the bifurcation diagram for the map x_(n+1)= x_n + (tn*r)+ rho* x_n*(1x_(n1)), n=0,1,2,..., t is the time should be between n*r and (n+1)*r. What's wrong in the code! I should have got a diagram not a point!!!
% define the vector of colors, to plot the dat aof reach value of r in % different color color_vec = ['b']; r=0.5; for rho = 0: 0.001:4 % define the number of deiscrete times in interval [k*r, (k+1)*r] n = 10; % define the nimber of iterations k = 1,.....,Nit Nit = 50; % define the initial vector which is a vector of size n x0 = 0.3*ones(1,n); % define vectors x_next and x_previous x_next = zeros(1,n); x_previous = zeros(1,n); %x_n x_pp=zeros(1,n); %x_n1 time = zeros(1,n);
% initialize x_previous %x_previous = x0; x_pp=0.2*ones(1,n); %x_n1 hold on for i = 1:Nit time = linspace(i*r,(i+1)*r,Nit); x_next = x_previous+(time(i)i.*r)*rho*x_pp.*(1x_pp); %x_previous = x_next; end end plot(rho,x_next(1),'b.') I need your help if you please. Thanks a lot in advance.
