I want to draw the bifurcation diagram fro the model. dy/dt=emxy/ (ax+by+c)-dy-hy^2. parameters are all +ve. I have tryed to plot it but fails. 2. Saddle-node bifurcation (x vs m & y vs. m) around at m = 20.8. 3. Hopf-bifurcation (x vs m & y vs. m) at m=14.73, (d,h) = (0.02,0.001) and others are same. In the [bifurcation diagram](https://upload.wikimedia.org/wikipedia/commons/5/50/Logistic_Bifurcation_map_High_Resolution.png) for the logistic map, it appears that there are some long curves of high density in the chaotic region. What are these curves and how do they arise?

How to draw bifurcation diagram

To construct the bifurcation diagram, we want to look at the values of the paramater alpha that produce equilibrium points for the differential equation. This means that we want to look at the values of alpha that make f equal to 0. The "implictplot" command generates a plot of the values of alpha and corresponding equilibrium points, as shown ... bifurcation diagram MATLAB I want to draw the bifurcation diagram for the model. All parameters are positve constant. The value of parameters are as: A1 = 0.8463, A2 = 0.6891, K = 1.2708, beta1 = 0.4110, beta2 = 0.1421, The diagram are vary tau from 68 to 72 in steps of 0.001. For inital conditions X (0) = 0.26 and Y (0) = 0.58. Or copy & paste this link into an email or IM:

How to draw bifurcation diagram. The bifurcation diagram should represent how the number, location, and stability of the equilibria depend on the value of α for − 23 ≤ α ≤ − 3. Draw curves to show the location of the equilibria as a function α. Use a solid line to indicate stable equilibria and a dashed line to indicate unstable equilibria. A more intuitive approach to orbits can be done through graphical representation using the following rules: Draw both curves on the same axes. Pick a point on the x-axis. This point is our seed. Draw a vertical straight line from the point until you intercept the parabola. In the following question, I am able to design a state feedback controller to stabilize the system. I am not sure how to go about sketching the bifurcation diagram. I have attached my solution for the first half of the question for reference. If any one could guide be on how to sketch the diagram would be really helpful [solution](https://preview.redd.it/aye1kr9nurr61.png?width=752&format=png&auto=webp&s=8c025db37b976da07b4244678b094e131a221535) [question](https://preview.redd.it/a... Hi all, I am pretty new to MATLAB as I just recently picked it up for this project. So far I have managed to figure out how to do everything except this last part. I have a system of three ODEs dx/dt = -y-z dy/dt = x+ay dz/dt = b + z(x-c) Where a,b,c are parameters. So what I am trying to do is create a 1D map that shows how the system behaves as two parameters are held constant and one varies. From my book that I am using (Strogatz, Nonlinear Dynamics and Chaos) I believe that what I have ...

I'm a beginner and I don't speak english very well so sorry about that. I'd like to draw the bifurcation diagram of the sequence : x(n+1)=ux(n)(1-x(n)) with x(0)=0.7 and u between 0.7 and 4. I am supposed to get something like this : So, for each value of u, I'd like to calculate the accumulation points of this sequence. Hi, I am having trouble solving what is the bifurcation of the given family map with the given parameter value? I need to use algebraic and/or graphical techniques to identify the type of bifurcation. Given: f(x)=x+cx\^2+x\^3, where c=0 Attempt: What I did was To find the fixed points I set Fc(x)=x that is x+cx\^2+x\^3=x cx\^2+x\^3=0 x\^2(c+x)=0 This gives fixed points x∗=0 and x∗=−c To find its stability I took the derivative of function fc(x) so f′c(x)=1+2cx+3x\^2 Using fixed points... From this I managed to calculate 3 bifurcation points, $(0,0)$, $(1,1)$ and $(\frac{2}{3},\frac{4}{3})$ Now this is where I got stuck, because surely I can't draw the bifurcation diagram without knowing the classification of each bifurcation point. So I tried to get the classification for each point. I know to be a saddle-node bifurcation: I've scoured the internet for pre-made bifurcation diagrams and found many (mostly of the logistic map). However, as the code is quite complicated I am not sure how to edit the code so that it deals with my function instead of the logistic one. Would anyone have a general template for the code to create a bifurcation diagram of a function?

The bifurcation diagram is constructed by plotting the parameter value k against all corresponding equilibrium values y ∗. Typically, k is plotted on the horizontal axis and critical points y* on the vertical axis. A "curve" of sinks is indicated by a solid line and a curve of sources is indicated by a dashed line.

I know that my code is not the most elegant, but for only learning python a few weeks ago I'm happy with it. I was expecting it to be a scatter plot, but I am only getting straight vertical lines, which doesn't seems to make sense to me. I was expecting some spread for either periodic solution or the chaotic solution, but I thought if the (a,x) coordinates were the same it would show up as a single dot on the graph. Anyway, hope my rambling isn't too off topic. Here is my code import matp...

Bifurcation Diagram r between 3.4 and 4 Notice that at several values of r, greater than 3.57, a small number of x=values are visited. These regions produce the 'white space' in the diagram. Look closely at r=3.83 and you will see a three-point attractor. In fact, between 3.57 and 4 there is a rich interleaving of chaos and order.
