1# Matrix colorings (MatColoring), orderings (MatOrdering), partitionings (MatPartitioning), and coarsening (MatCoarsen) 2 3These tools compute reorderings (`MatOrdering`) (for sparse matrix factorizations), colorings (`MatColoring`) 4(for computing Jacobians via finite differences), partitionings (`MatPartitioning`) (for parallel 5decomposition of data), and coarsening (`MatCoarsen`) (for algebraic multigrid methods). 6
