Default help for 2D numerical sol of diffusion equation
Posts: n/a
I am trying to write a matlab code to get the solution (steady state solution (implicit and explicit)) for the 2D diffusion equation. the fact is I am not really familiar with matlab. I think I have an equation which could be ok:

for i=2:nh-1

for j=2:nh-1






my problem is to implement the boundary conditions, the initial condition...

I hope someone can help me thank you
