Detailed Description

template<class Scalar>
class Thyra::DiagonalLinearOpBase< Scalar >

Interface class for for diagonal linear operators.

This interface represents a diagonal linear operator M of the form:

M = diag(diag)

where diag is a VectorBase object.

The operator subclass must implement apply() as follows:

y = alpha*op(M)*x + beta*y

=>

y(i) = alpha*diag(i)*x(i) + beta*y(i), for i = 0 ... n-1

where n = this->domain()->dim().

Member Function Documentation

template<class Scalar >

virtual bool Thyra::DiagonalLinearOpBase< Scalar >::isDiagConst ( ) const

pure virtual

Returns true if the diagonal vector is const-only.

Implemented in Thyra::DefaultDiagonalLinearOp< Scalar >.

template<class Scalar >

virtual Teuchos::RCP<VectorBase<Scalar> > Thyra::DiagonalLinearOpBase< Scalar >::getNonconstDiag ( )

pure virtual

Returns the non-const diagonal vector diag.

Preconditions:

• [getDiag().get()!=NULL] isDiagConst()==false

Note that *this is not guaranteed to be fully modified until the RCP returned is deleted.

A return value of return.get()==NULL indicates that this is not fully initialized.

Implemented in Thyra::DefaultDiagonalLinearOp< Scalar >.

template<class Scalar >

virtual Teuchos::RCP<const VectorBase<Scalar> > Thyra::DiagonalLinearOpBase< Scalar >::getDiag ( ) const

pure virtual

Returns the const diagonal vector diag.

A return value of return.get()==NULL indicates that this is not fully initialized.

Implemented in Thyra::DefaultDiagonalLinearOp< Scalar >.
