Detailed Description

template<class Scalar, class LocalOrdinal, class GlobalOrdinal, class Node>
class Tpetra::BlockCrsMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >

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

This class takes the same template parameters as BlockCrsMatrix.

(

)

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

Teuchos::RCP< BlockCrsMatrix< Scalar, LocalOrdinal, GlobalOrdinal, Node > > Tpetra::BlockCrsMatrixTransposer< Scalar, LocalOrdinal, GlobalOrdinal, Node >::createTransposeLocal

(

const Teuchos::RCP< Teuchos::ParameterList > &

params = Teuchos::null

)

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.
