41 how to draw a bifurcation diagram
Hello, I am new to Wolfram Mathematica, and I try to work with it to plot bifurcation diagram. The quest is to plot lines that are continous in one range and dashed in another range. The key point is that there is a function that gives me the information whether the line is continous (stable) or dashed (unstable). you can use mathematical for it.drawing bifurcation diagram and etc is very easy.

The Bifurcation Diagram. A very helpful way to illustrate bifurcations is through a Bifurcation Diagram. Again we will illustrate this tool via the harvesting example. ... Let us draw this on a diagram with two axes on the horizontal axis, we will put the parameter H; on the vertical axis, we will have the values of P, giving the constant ...

1.2 Bifurcation. All diagrams rendered with 1‑D Chaos Explorer. 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. Introduction to a bifurcation diagram. Find the bifurcation values and describe how the behavior of the solutions changes close to each bifurcation value. Repeat step 2 with this new point. Draw curves to show the location of the equilibria as a function. Is there any formula to plot the bifurcation diagram.

Bifurcation diagrams are an effective way of representing the nature of the solutions of a one-parameter family of differential equations. Bifurcations for a one-parameter family of differential equations \(dx/dt = f_\lambda(x)\) are rare.

A Bifurcation Diagram is a visual summary of the succession of period-doubling produced as r increases. The next figure shows the bifurcation diagram of the logistic map, r along the x-axis. For each value of r the system is first allowed to settle down and then the successive values of x are plotted for a few hundred iterations. I am trying to generate a bifurcation diagram for a predator prey interaction but I am struggling to find a way to plot it. This is the problem: Suppose the solution for the differential equations that describes the dynamic of the predator and the prey after a fixed number of iteration steps (to avoid transient) is unique, the dynamics are stable. Drawing bifurcation diagram for 1D system is clear but if I have 2D system on the following form dx/dt=f(x,y,r), dy/dt=g(x,y,r) And I want to generate a bifurcation diagram in MATLAB for x versus r. What is the main idea to do that or any hints which could help me? matlab diagram matlab-figure. Share. Follow edited May 21 '12 at 22:38.

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.

An example is the bifurcation diagram of the logistic map: + = (). The bifurcation parameter r is shown on the horizontal axis of the plot and the vertical axis shows the set of values of the logistic function visited asymptotically from almost all initial conditions.. The bifurcation diagram shows the forking of the periods of stable orbits from 1 to 2 to 4 to 8 etc.

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?

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.
