Does my code make sense? It runs without errors, but I'm not sure if I did the right thing.

Hi all. On the attached code, I am interested in solving for x (using the @xfun function) and solving for y(1)...y(6), using the @odes function. I have to repeat the calculation 30 times, where for the next time step, I must use the preceding x(i) to solve for y(i+1). Similarly, I must use y(i) to find x(i+1). I have to march on 30 steps in that manner. I am not sure if my code is doing exactly that, however it runs without error, and it gives results.

I thank you.

Your code will give the same results if you just delete the for-loop. So I guess there must be something wrong with your programming.

Thanks for the response Torsten. How can I ensure that it uses x(i) to calculate y(i+1), and likewise that it uses y(i) to calculate x(i+1)? Is there any other way than to use the for-loop? Is it common to use ode45 solver?

[Torsten]

I don't see in your code how you find x(i+1) from y(i).

[Dursman Mchabe]

I thought, the for-loop is serving that purpose. That is exactly where I am not sure. What is the recommendable way?

[Torsten]

I can't give you a recommendation because I don't know how x(i+1) depends on y(i).
