Xpetra: need a RowMatrixTransposer
Created by: mayrmt
Xpetra::RowMatrixTransposer that explicitly forms the transpose of a given
Tpetra::RowMatrixTransposer are implemented and tested, but are not accessible through
Motivation and Context
Forming the transpose of a matrix explicitly sometimes is useful.
This is required for #4084 (closed).
Definition of Done
- Implement Xpetra interface to access Epetra/Tpetra version of a RowMatrixTransposer.
- Add unit test.
Tpetra::RowMatrixTransposer already exist and are tested. We could just add an
Xpetra::RowMatrixTransposer and derived classes
Xpetra::TpetraRowMatrixTransposer that internally call the respective EpetraExt/Tpetra functionality.
- Blocks #4084 (closed)
