How to make Galerkin coarse operator in multigrid?
In multigrid, the coarse operator is given by $$A^{2h}=RA^hP$$
where $R$ is a restriction and $P$ is a interpolation. In 1D case, I can implement it easily with or without making explicitly matrix $A^{2h}$. For the 2D case of Poisson equation, I can…
