Constructor.
- Parameters
-
maxLevel The maximum number of levels allowed in the matrix hierarchy (default: 100). coarsenTarget If the number of nodes in the matrix is below this threshold the coarsening will stop (default: 1000). minCoarsenRate If the coarsening rate falls below this threshold the coarsening will stop (default: 1.2) prolongDamp The damping factor to apply to the prolongated update (default: 1.6) accumulate Whether to accumulate the data onto fewer processors on coarser levels.
