Public Member Functions

 Ifpack_METISReordering ()
 Constructor.
virtual ~Ifpack_METISReordering ()
 Destructor.
virtual int SetParameter (const string Name, const int Value)
 Sets integer parameters `Name'.
virtual int SetParameter (const string Name, const double Value)
 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 ostream & Print (std::ostream &os) const
 Prints basic information on iostream. This function is used by operator<<.
