Detailed Description

template<class Scalar = CrsMatrix<>::scalar_type, class LocalOrdinal = typename CrsMatrix<Scalar>::local_ordinal_type, class GlobalOrdinal = typename CrsMatrix<Scalar, LocalOrdinal>::global_ordinal_type, class Node = typename CrsMatrix<Scalar, LocalOrdinal, GlobalOrdinal>::node_type>
class Tpetra::RowMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Construct and (optionally) redistribute the explicitly stored transpose of a CrsMatrix.

This class is based on the EpetraExt version. It first transposes the matrix to an intermediate version with overlapping row map. That matrix is then converted to a final version whose row map is "unique", i.e., a row is wholly owned by one process.

This class takes the same template parameters (with the same default values) as CrsMatrix.

Tpetra::RowMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >::RowMatrixTransposer

Constructor that takes the matrix to transpose.

TEUCHOS_DEPRECATED Tpetra::RowMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >::RowMatrixTransposer

(

const crs_matrix_type &

origMatrix

)

Constructor that takes the matrix to transpose (DEPRECATED).

This method is DEPRECATED, because it is not memory safe. (If origMatrix falls out of scope, its reference will be invalidated.) Please call the version of the constructor that takes an RCP<const crs_matrix_type>.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

Teuchos::RCP< CrsMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node > > Tpetra::RowMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >::createTranspose

(

)

Compute and return the transpose of the matrix given to the constructor.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

Teuchos::RCP< CrsMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node > > Tpetra::RowMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >::createTransposeLocal

(

)

Compute and return the transpose of the matrix given to the constructor.

In this call, we (potentially) leave the matrix with an overlapping row Map. This is a perfectly valid matrix, but won't work correctly with some routines in Ifpack or Muelu.

Warning:

This routine leaves overlapping rows. Unless you're sure that's OK, call createTranspose() instead.
