Web1 Answer. It seems like you'll get the boundary conditions you want automatically if you construct your discrete Laplacian in terms of an adjacency matrix, minus the sum of the number of neighbors along the diagonal. In the interior, the discrete Laplacian is { 1, − 2, 1 }. That is, the adjacent cells { 1, 0, 1 } minus their sum ( − 2 ...
