Ifpack_Graph: a pure virtual class that defines graphs for IFPACK.
Ifpack_RCMReordering: reverse Cuthill-McKee reordering.
virtual std::ostream & Print(std::ostream &os) const
Prints basic information on iostream. This function is used by operator<<.
virtual int Pinv(const Epetra_MultiVector &Xorig, Epetra_MultiVector &Xinvreord) const
Applies inverse reordering to multivector X, whose local length equals the number of local rows.
virtual int SetParameters(Teuchos::ParameterList &List)
Sets all parameters.
virtual int NumMyRows() const
Returns the number of local rows.
virtual int SetParameter(const std::string Name, const int Value)
Sets integer parameters ‘Name’.
virtual bool IsComputed() const
Returns true is the reordering object has been successfully initialized, false otherwise.
Ifpack_RCMReordering & operator=(const Ifpack_RCMReordering &RHS)
Assignment operator.
virtual int InvReorder(const int i) const
Returns the inverse reordered index of row i.
virtual ~Ifpack_RCMReordering()
Destructor.
Ifpack_RCMReordering()
Constructor for Ifpack_Graph's.
virtual int RootNode() const
Returns the root node.
virtual int Reorder(const int i) const
Returns the reordered index of row i.
virtual int P(const Epetra_MultiVector &Xorig, Epetra_MultiVector &Xreord) const
Applies reordering to multivector X, whose local length equals the number of local rows.
virtual int Compute(const Ifpack_Graph &Graph)
Computes all it is necessary to initialize the reordering object.
Ifpack_Reordering: basic class for reordering for a Ifpack_Graph object.
