Detailed Description

template<class Scalar = double, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::DropNegativeEntriesFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Application-specific filtering for A. Can be used in context of graph coarsening and aggregation.

This factory drops all negative entries (or entries with a magnitude < 0). Only weak positive connections are kept. Do not use this kind of filtering for regular PDEs unless you have very good reasons.
