Epetra_Timed_Operator(const Teuchos::RCP< Epetra_Operator > &A_)
Constructor.
virtual bool HasNormInf() const
Returns true if the this object can provide an approximate Inf-norm, false otherwise.
int SetUseTranspose(bool useTranspose)
Set to true if the transpose of the operator is requested.
Teuchos::RCP< Teuchos::Time > ApplyTimer
Keeps track of the apply time.
virtual const Epetra_Comm & Comm() const
Returns a reference to the Epetra_Comm communicator associated with this operator.
virtual double NormInf() const
Returns an approximate infinity norm of the operator matrix.
virtual bool UseTranspose() const
Returns the current UseTranspose setting.
virtual int Apply(const Epetra_MultiVector &Input, Epetra_MultiVector &Result) const
