NM10 4 Finite Difference Method nonlinear

[@ndestr0yr]

This video is master-class. Greatly appreciated!

Awesome video sir! Thank you! You're the only one who tackled nonlinear BVPs for the finite difference method in KZbin. Thank you so much.

Thanks Eric. I did a brush up about FD NLDE using NR watching your clear video.

2:22, that should be T(i-1)

Can you please tell me how do you set up NRsys function there? Thank you 🙏

At 4:03, even when correcting T_(i+1) to T_(i-1), there's no way that your two first equations are equal (tested with isAlways() in MATLAB): eq1 = (Tprev - 2*Ti + Tnext)/(dx^2) + h*(Tinf - Ti) + sigma*(Tinf^4 - Ti^4) eq2 = Tprev - (2 + dx^2 * h)*Ti - dx^2 * sigma * Ti^4 + Tnext + dx^2*(h * Tinf + sigma * Tinf^2) Or is there something I have grossly misunderstood? When solving for the jacobian of eq1 in MATLAB you get: [ 1/dx^2, - h - 4*Ti^3*sigma - 2/dx^2, 1/dx^2]

Hi. I the very first hand equation in differences, one term must be Ti-1. right ?

[@theophiluskwofie6323]

Please, could you help me to create NRsys function?

How can I ask you about something?
