Forward declaration of Tpetra::CrsMatrix.
Forward declaration of Tpetra::Map.
Forward declaration of Tpetra::RowMatrixTransposer.
Sparse matrix that presents a row-oriented interface that lets users read or modify entries.
A parallel distribution of indices over processes.
Construct and (optionally) redistribute the explicitly stored transpose of a CrsMatrix.
Teuchos::RCP< crs_matrix_type > createTranspose(const Teuchos::RCP< Teuchos::ParameterList > &params=Teuchos::null)
Compute and return the transpose of the matrix given to the constructor.
Teuchos::RCP< crs_matrix_type > createTransposeLocal(const Teuchos::RCP< Teuchos::ParameterList > &params=Teuchos::null)
Compute and return the transpose of the matrix given to the constructor.
RowMatrixTransposer(const Teuchos::RCP< const crs_matrix_type > &origMatrix, const std::string &label=std::string())
Constructor that takes the matrix to transpose.
Namespace Tpetra contains the class and methods constituting the Tpetra library.
