Solve Ordinary Differential Equations in Matlab

Thanks for uploading these tutorials.
It is a very nice way of learning matlab.
Because of these videos I got an A in my matlab examination.
Thanks again.

I apreciate it

Very helpful, I watched almost all videos you published, thanks very much for your great work.

very good tutorial.

when I solve the kdv equation, I impose for the equation to decay at both -inf and +inf.

how could I solve a similar problem that I change from a pde to a system of 2 odes.
I will like to impose that the function goes to zero at +inf.

I can bring the problem out of my old folders, if you can guide me on it.

thank you very much

I'm not familiar with the KdV equation. A quick Google search shows some approaches for reducing to an ODE. I can take a look at it, if you send me more details. Feel free to email me directly:

lets forget about pdes.

I have 2 odes, a system of 2 odes that I want to solve in matlab, so I will get that equation and bring it to you, so that you can see it.

all I want to do is to the solution of the system of odes is to approach 0 as we move to postitive infinity.

hence the reason I ask about how to impose a certain condition to a solution solve in matlab, in this case is imposing that our solution goes to zero at positive infinity.

What if you solve them as a boundary value problem. Then you can force the solution to go to zero at some large value of x. Of course, you would have to give up on some initial condition. Interesting problem. I think you have the same problem with an analytical solution.

Send me specifics.

damn i cant believe i found this. haha good work man and thanks a bunch

nice

Thank you ,thank you, thank you
