Discretize the elliptic PDE
Combining the row vectors
sequentially
to a vector
of length we may write these equations in the
form
where
is a sparse matrix, and where the vector
contains the charge density and the given boundary
values of the potential function .
Solve by applying any of the Relaxation Methods.
