Detailed Description

template<class Scalar = Xpetra::Matrix<>::scalar_type, class LocalOrdinal = typename Xpetra::Matrix<Scalar>::local_ordinal_type, class GlobalOrdinal = typename Xpetra::Matrix<Scalar, LocalOrdinal>::global_ordinal_type, class Node = typename Xpetra::Matrix<Scalar, LocalOrdinal, GlobalOrdinal>::node_type>
class MueLu::ShiftedLaplacian< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Shifted Laplacian Helmholtz solver.

This class provides a black box solver for indefinite Helmholtz problems. An AMG-Shifted Laplacian is used as a preconditioner for Krylov iterative solvers in Belos.
