Constructor. | |
virtual | ~Ifpack_METISReordering () |
Destructor. | |
virtual int | SetParameter (const std::string Name, const int Value) |
Sets integer parameters `Name'. | |
virtual int | SetParameter (const std::string, const double) |
Sets double parameters `Name'. | |
virtual int | SetParameters (Teuchos::ParameterList &List) |
Sets all the parameters for the partitioner (none at moment). | |
virtual int | Compute (const Ifpack_Graph &Graph) |
Computes all it is necessary to initialize the reordering object. | |
virtual int | Compute (const Epetra_RowMatrix &Matrix) |
Computes all it is necessary to initialize the reordering object. | |
virtual bool | IsComputed () const |
Returns true is the reordering object has been successfully initialized, false otherwise. | |
virtual int | Reorder (const int i) const |
Returns the reordered index of row i . | |
virtual int | InvReorder (const int i) const |
Returns the inverse reordered index of row i . | |
virtual int | P (const Epetra_MultiVector &Xorig, Epetra_MultiVector &X) const |
Applies reordering to multivector Xorig, whose local length equals the number of local rows, stores result in X. | |
virtual int | Pinv (const Epetra_MultiVector &Xorig, Epetra_MultiVector &X) const |
Applies inverse reordering to multivector Xorig, whose local length equals the number of local rows, stores result in X. | |
virtual std::ostream & | Print (std::ostream &os) const |
Prints basic information on iostream. This function is used by operator<<. | |
