Detailed Description

template<class BaseScalar, class Storage, class LO, class GO, class Node>
class Belos::MultiVecTraits< BaseScalar, Tpetra::MultiVector< Sacado::MP::Vector< Storage >, LO, GO, Node > >

Partial specialization of MultiVecTraits for MV = Tpetra::MultiVector.

This interface lets Belos' solvers work directly with Tpetra::MultiVector objects as the multivector type (corresponding to the MV template parameter).

The four template parameters of this partial specialization correspond exactly to the four template parameters of Tpetra::MultiVector. See the Tpetra::MultiVector documentation for more information.

template<class BaseScalar , class Storage , class LO , class GO , class Node >

static Teuchos::RCP<Tpetra::MultiVector<Scalar,LO,GO,Node> > Belos::MultiVecTraits< BaseScalar, Tpetra::MultiVector< Sacado::MP::Vector< Storage >, LO, GO, Node > >::Clone	(	const Tpetra::MultiVector< Scalar, LO, GO, Node > &	mv,
		const int	numvecs
	)		[inline, static]

Create a new multivector with numvecs columns.

The returned Tpetra::MultiVector has the same Tpetra::Map (distribution over one or more parallel processes) as mv. Its entries are not initialized and have undefined values.

template<class BaseScalar , class Storage , class LO , class GO , class Node >

static void Belos::MultiVecTraits< BaseScalar, Tpetra::MultiVector< Sacado::MP::Vector< Storage >, LO, GO, Node > >::MvAddMv	(	Scalar	alpha,
		const Tpetra::MultiVector< Scalar, LO, GO, Node > &	A,
		Scalar	beta,
		const Tpetra::MultiVector< Scalar, LO, GO, Node > &	B,
		Tpetra::MultiVector< Scalar, LO, GO, Node > &	mv
	)		[inline, static]

mv := alpha*A + beta*B

The Tpetra specialization of this method ignores and completely overwrites any NaN or Inf entries in A. Thus, it does not mean the same thing as mv := 0*mv + alpha*A + beta*B in IEEE 754 floating-point arithmetic. (Remember that NaN*0 = NaN.)
