Detailed Description

template<class Scalar = DefaultScalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::SubBlockAFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for building a thresholded operator.

This is a very simple class to access a single matrix block in a blocked operator A.

Example

Teuchos::RCP<Xpetra::BlockedCrsMatrix<Scalar,LO,GO,Node> > bOp = Teuchos::rcp(new Xpetra::BlockedCrsMatrix<Scalar,LO,GO>(mapExtractor,mapExtractor,10));
// ... let bOp be a 2x2 blocked operator ...
bOp->fillComplete();
// define factory for accessing block (0,0) in blocked operator A (assuming that the blocked operator is stored in Level class with NoFactory as generating factory)
RCP<SubBlockAFactory> A11Fact = Teuchos::rcp(new SubBlockAFactory());
A11Fact->SetFactory("A", MueLu::NoFactory::getRCP());
A11Fact->SetParameter("block row", 0);
A11Fact->SetParameter("block col", 0);
// define factory for accessing block (1,1) in blocked operator A
RCP<SubBlockAFactory> A22Fact = Teuchos::rcp(new SubBlockAFactory());
A22Fact->SetFactory("A", MueLu::NoFactory::getRCP());
A22Fact->SetParameter("block row", 1);
A22Fact->SetParameter("block col", 1);
RCP<Matrix> A11 = level.Get<RCP<Matrix> >("A", A11Fact); // extract (0,0) block from blocked operator A
RCP<Matrix> A22 = level.Get<RCP<Matrix> >("A", A22Fact); // extract (1,1) block from blocked operator A

Specifies the data that this class needs, and the factories that generate that data.

If the Build method of this class requires some data, but the generating factory is not specified in DeclareInput, then this class will fall back to the settings in FactoryManager.

void MueLu::SubBlockAFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Build ( Level & currentLevel ) const

virtual

Build an object with this factory.

Extract sub block matrix from a given blocked crs operator. Strided or block information is extracted in the following way: 1) first check whether the corresponding sub maps are strided If yes, use the fixed block size and strided block id 2) If no, get the full map of the map extractors. Check whether the full map is strided. If yes, use the strided information of the full map and build partial (strided) maps with it If no, throw an exception

For blocked operators with block maps one should use the striding information from the sub maps. for strided operators, the striding information of the full map is the best choice.
