Struct that holds views of the contents of a CrsMatrix.
Abstract interface for operators (e.g., matrices and preconditioners).
A class for wrapping an Operator apply in a Operator.
virtual ~ApplyOp()
Destructor.
ApplyOp(const Teuchos::RCP< const OperatorType > &op)
Constructor.
OperatorType::global_ordinal_type global_ordinal_type
The type of global indices in the input OperatorType.
Teuchos::RCP< const OperatorType > operator_
The underlying Operator object.
OperatorType::scalar_type scalar_type
The type of the entries of the input OperatorType.
OperatorType::local_ordinal_type local_ordinal_type
The type of local indices in the input OperatorType.

Compute Y = beta*Y + alpha*Op(A)*X, where Op(A) is either A, , or .
Teuchos::RCP< const Tpetra::Map< local_ordinal_type, global_ordinal_type, node_type > > getDomainMap() const
The domain Map of this Operator.
Teuchos::RCP< const Tpetra::Map< local_ordinal_type, global_ordinal_type, node_type > > getRangeMap() const
The range Map of this Operator.
bool hasTransposeApply() const
Whether this Operator's apply() method can apply the transpose or conjugate transpose.
OperatorType::node_type node_type
The type of the Kokkos Node used by the input OperatorType.
