int	Compute (const Epetra_RowMatrix &Matrix)
	Computes all it is necessary to initialize the reordering object.

bool	IsComputed () const
	Returns `true` is the reordering object has been successfully initialized, false otherwise.

int	Reorder (const int i) const
	Returns the reordered index of row `i`.

int	InvReorder (const int i) const
	Returns the inverse reordered index of row `i`.

int	P (const Epetra_MultiVector &Xorig, Epetra_MultiVector &Xreord) const
