Teuchos::RCP<const Tpetra::Map<int, SupportId> > DataTransferKit::PolynomialMatrix::getDomainMap ( ) const

inlineoverride

The Map associated with the domain of this operator, which must be compatible with X.getMap().

Definition at line 75 of file DTK_PolynomialMatrix.hpp.

Teuchos::RCP<const Tpetra::Map<int, SupportId> > DataTransferKit::PolynomialMatrix::getRangeMap ( ) const

inlineoverride

The Map associated with the range of this operator, which must be compatible with Y.getMap().

Definition at line 82 of file DTK_PolynomialMatrix.hpp.

void DataTransferKit::PolynomialMatrix::apply	(	const Tpetra::MultiVector< double, int, SupportId > &	X,
		Tpetra::MultiVector< double, int, SupportId > &	Y,
		Teuchos::ETransp	mode = `Teuchos::NO_TRANS`,
		double	alpha = `Teuchos::ScalarTraits<double>::one()`,
		double	beta = `Teuchos::ScalarTraits<double>::zero()`
	)		const

override

Computes the operator-multivector application.

Loosely, performs $Y = \alpha \cdot A^{\textrm{mode}} \cdot X + \beta \cdot Y$ . However, the details of operation vary according to the values of alpha and beta. Specifically - if beta == 0, apply() must overwrite Y, so that any values in Y (including NaNs) are ignored. - if alpha == 0, apply() may short-circuit the operator, so that any values in X (including NaNs) are ignored.
