For BCs, I think we have create the matrix of equations for x = [2, N-1] and y [2,N-1] bc the first and last row/column is reserved for whatever the values should be at the boundaries.
You take the differential operator and convert it to polar coordinates. Then you plug in for the coefficients which the polar coordinate form gives. You can look up the polar coordinate forms easily.
Didn't mention any boundary conditions !!

Hi, what if we have boundary condition? how can we define the vector?
I have a question. How to enter the limits of "x" and "y"?
Excelent videos, how can I make this work in polar coordinates?
Or should I use a different method like the finite element method? Cause I've been using the finite differences method

too good man
I follow exactly the same steps with the same f, but somehow my u is inf... why did it happen?
That usually means that your matrix A is singular. Can you check, after you construct your matrix, that all diagonal entries are nonzero?
use to pdetool to solve differential equations dude.
