Dear all, I came up to the naive question which is contradictive, i.e.
How to parallelize upwind scheme?
Suppose, we have the following implementation of upwind
for k = 1:kFin % time-loop
% space-loop
un(2:nx) = u(2:nx) - cfl*(u(2:nx) - u(1:nx-1));
% BC
un(1) = un(nx);
% update
u = un;
end % for
So, how to parallelize it via parfor or spmd or else?
Is it possible for such schemes?

Dear Walter,
Thank you for reply.
I thought that number is a scalar, but it could be a vector of matrix if it's necessary for sure. Suppose is a constant value for simplicity.
