Factory for building a new "segregated" A operator. Here, "segregated" means that the user provides a map (containing a subset of the row gids of the input matrix A) and the factory drops the off-diagonal entries (a,b) and (b,a) in A where "a" denotes a GID entry in the provided map and "b" denotes a GID that is not contained in the provided map.

Detailed Description

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

Factory for building a new "segregated" A operator. Here, "segregated" means that the user provides a map (containing a subset of the row gids of the input matrix A) and the factory drops the off-diagonal entries (a,b) and (b,a) in A where "a" denotes a GID entry in the provided map and "b" denotes a GID that is not contained in the provided map.

The idea is to use the output matrix A as input for the aggregation factory to have control over the aggregates and make sure that aggregates do not cross certain areas.

Note: we have to drop the entries (i.e. not just set them to zero) as the CoalesceDropFactory does not distinguish between matrix entries which are zero and nonzero.
