int EpetraExt_HypreIJMatrix::ApplyInverse	(	const Epetra_MultiVector &	X,
		Epetra_MultiVector &	Y
	)		const

inlinevirtual

Returns the result of a Epetra_Operator inverse applied to an Epetra_MultiVector X in Y.

In this implementation, we use several existing attributes to determine how virtual
method ApplyInverse() should call the concrete method Solve().  We pass in the UpperTriangular(),

the EpetraExt_HypreIJMatrix::UseTranspose(), and NoDiagonal() methods. The most notable warning is that if a matrix has no diagonal values we assume that there is an implicit unit diagonal that should be accounted for when doing a triangular solve.

Parameters

X	(In) - A Epetra_MultiVector of dimension NumVectors to solve for.
Y	(Out) -A Epetra_MultiVector of dimension NumVectors containing result.

Returns: Integer error code, set to 0 if successful.

virtual

Return the current number of values stored for the specified local row.

Similar to NumMyEntries() except NumEntries is returned as an argument
