Namespace Tpetra contains the class and methods constituting the Tpetra library.
Scalar scalar_type
The type of the entries of the input and output multivectors.
Node node_type
The Kokkos Node type.
KokkosClassic::DefaultNode::DefaultNodeType node_type
Default value of Node template parameter.
One or more distributed dense vectors.
virtual void apply(const MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &X, MultiVector< Scalar, LocalOrdinal, GlobalOrdinal, Node > &Y, Teuchos::ETransp mode=Teuchos::NO_TRANS, Scalar alpha=Teuchos::ScalarTraits< Scalar >::one(), Scalar beta=Teuchos::ScalarTraits< Scalar >::zero()) const =0
Computes the operator-multivector application.
virtual Teuchos::RCP< const Map< LocalOrdinal, GlobalOrdinal, Node > > getRangeMap() const =0
The Map associated with the range of this operator, which must be compatible with Y...
int local_ordinal_type
Default value of LocalOrdinal template parameter.
Declaration of the Tpetra::MultiVector class.
Abstract interface for operators (e.g., matrices and preconditioners).
virtual Teuchos::RCP< const Map< LocalOrdinal, GlobalOrdinal, Node > > getDomainMap() const =0
The Map associated with the domain of this operator, which must be compatible with X...
GlobalOrdinal global_ordinal_type
The global index type.
double scalar_type
Default value of Scalar template parameter.
virtual bool hasTransposeApply() const
Whether this operator supports applying the transpose or conjugate transpose.
LocalOrdinal local_ordinal_type
The local index type.
