Much helpful

How can I code three systems of ODEs?

Masterfully executed!

ok cool video but does it generatate good images?

how x1= 0??

Arigato sensei

Thanks a lot. It's helpfull for me

thanks professor compact and to the point

Great explanation, thank you sir

Good explanation, but Im wondering why you erased S1+S2/2 to write S1+S1/2 which doesn't look logical

AMAN AJAA

The tutorial was really helpful. It greatly simplified the code length. I even changed from row vector mode to column vector mode and it worked as well!! Many many thanks to you sir!

Your a god among men

That's really fantastic. thank you sir....

thank u so much sir

awesome video thanks

It was very helpful for my project sir. Thanks a lot.

Great video!

Thanks for great quality content

Very helpful!!! Thank you so much!!!

thank you so much for this.

Helps a Lot, Thank you very very much. Keep making videos. Your knowledge is the best, keep sharing. Thanks.

How can I get the code of 4th-Order Runge-Kutta Method for solving integral equations?

Sir You are really great

THANK YOU!!!! For those wondering about dx ~= dy line 25 == -2*( (dx/dy)^2 +1) line 28&29== (dx/dy)^2 I believe this is all that is needed. I could be wrong. I'm a rookie.

THANK YOU!!!!

Can I apply this code for nonlinear coupled ode

LIFE SAVER

Can you give this Matlab code?

Can you give this Matlab code?

May God reward you for all your efforts and all the valuable information that you provide us smoothly .

Thanks for the video, helped me with my research project so much!

thank you so much , sir.

Actually truncation error's components are local and propagated error, summation of these two gives the global truncation error as far as I know. Am ı wrong?

Would have been very nice to have pasted the code in the description as well.

Thank u so much,

You are the best

very ...approximative work. Not rigourous. Bad video

How can I define the boundary in my case 1000, 500, 50, and 0 ?. how can I apply it in the code ? some one please help me :)

Simple and clear. Thanks.

Thanks

These videos are excellent and easy to follow and implement. Prof Owkes any reference text that you can recommend for these topics, especially the finite difference method

Do you have any video on Method of Lines?

Sir, please solve the same using finite element method. Thank you

Thank you very much!!!

so your using my method because my last name is heun?

nice videos. this is such a great help that i can understand matlab PDE coding.

Sir, Is this also equal to first order RK method simultaneous equation?

with matlab
