Constructor & Destructor Documentation

DirectSolverOperator::DirectSolverOperator	(	Epetra_RowMatrix &	A,
		Teuchos::ParameterList &	params
	)

Constructor

Parameters:

	A	Epetra_RowMatrix to factorise. The resulting operator also inherits the domain and range maps and the communicator from it.
	params	A Teuchos::ParameterList containing parameters for the direct solver.
