Thank you for reply. I have another doubt, how to find and plot minimum eigenvalue for stability analysis using bvp4c method my code is not running for finding eigenvalues please help me.

Thank you this video is very helpful to understanding for bvp4c methode code. Why you use exponential function for the initial gausses in 2nd solution? We can't use any number for second solution initial gauss like first solution initial gauss?
@nswahid Жыл бұрын
You're welcome. Yes, you can actually try any value for the initial guesses. I use exp(-x) as to give a small value to the guesses. And, make sure the value of the guesses for the first and the second is different, if you want to generate more that one solution (e.g., dual solutions)

Mam how to put for diffusion equation by bvp4
@nswahid Жыл бұрын
Supposedly, if you have the diffusion equation in the form of ODE, you can apply the same procedure as this one.

Thank you so much for sharing such a masterpiece. I was struggling to get eta out of the structure form for so long but didn't get that correctly. Now I got the answer. Thanks alot. Your code is too clear and precise. 👍 I've some questions. 1. Is there any way to find initial values and critical points. Or the method you used in this video is the only way?
@nswahid Жыл бұрын
Do you mean the initial value for the parameter or the initial guesses? If for the initial guesses, I can't point out any absolute guess value, it depends on the problem which you need to undergo several trial-and-error processes till you obtain the best result that satisfies the boundary conditions. And, for the critical point, it is actually the last possible point that you can obtain for certain specific configurations. So, yes, for now, this is the method that I know. I hope this helps.

Thanks a lot ...i ask how can i solve this problem : MATLAB : Jacobi : singoler ?
@nswahid 2 жыл бұрын
Do you mean the error? Maybe you need to adjust the value of the parameters e.g. try to make them small, or adjust the initial guesses.

I guess, yes. It can be unsolvable if the initialization value doesn't meet the convergent criteria.

Hi, I'm just curious why don't you used direct command to get skin friction as a function of Lambda for varying A? Second, you are manually updating the tables or they are done through some codes? Thanks
@nswahid 2 жыл бұрын
Hi. I'm not sure what do you mean by direct command, but as for now, the command that I used is as shown in 'Tutorial 2' video. Yes, the tables need to be updated manually for each point, for varying parameters.
