Belos::MueLuOp< Scalar, LocalOrdinal, GlobalOrdinal, Node > Class Template Reference

MueLuOp derives from Belos::OperatorT and administrates a MueLu::Hierarchy. It implements the apply call which represents the effect of the multigrid preconditioner on a given vector. Note, in contrast to Belos::XpetraOp this operator has the multigrid hierarchy. More...

Detailed Description

template<class Scalar, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class Belos::MueLuOp< Scalar, LocalOrdinal, GlobalOrdinal, Node >

MueLuOp derives from Belos::OperatorT and administrates a MueLu::Hierarchy. It implements the apply call which represents the effect of the multigrid preconditioner on a given vector. Note, in contrast to Belos::XpetraOp this operator has the multigrid hierarchy.

The Belos::OperatorT class is a generalization of the Belos::Operator<> class, which deals with any kind of vector (not only Belos::MultiVec as the Belos::Operator<> interface does).

This is the general implementation for Tpetra only.

Member Function Documentation

void Belos::MueLuOp< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Apply ( const Xpetra::MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &  x,
Xpetra::MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &  y,
ETrans  trans = NOTRANS 
) const
inline

This routine takes the Xpetra::MultiVector x and applies the operator to it resulting in the Xpetra::MultiVector y, which is returned.

Note
It is expected that any problem with applying this operator to x will be indicated by an std::exception being thrown.
