Detailed Description

template<class Scalar>
class Thyra::DefaultDiagonalLinearOp< Scalar >

Default concrete LinearOpBase subclass for diagonal linear operators.

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

M = diag(diag)

where diag is a VectorBase object.

The defined operator implements this->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 >

void Thyra::DefaultDiagonalLinearOp< Scalar >::initialize ( const RCP< const VectorSpaceBase< Scalar > > & space )

Initialize given a vector space which allocates a vector internally.

Parameters

space [in] Smart pointer to vector space

Preconditions:

space.get()!=NULL

Postconditions:

this->getNonconstDiag()->space()->isCompatible(*space)==true
this->getDiag()->space()->isCompatible(*space)==true
this->this->domain().get() == space.get()
this->this->range().get() == space.get()

template<class Scalar >

void Thyra::DefaultDiagonalLinearOp< Scalar >::initialize ( const RCP< VectorBase< Scalar > > & diag )

Initialize given a non-const diagonal vector.

Parameters

diag	[in] Smart pointer to diagonal vector.

Preconditions:

diag.get()!=NULL

Postconditions:

this->getNonconstDiag().get()==diag.get()
this->getDiag().get()==diag.get()
this->this->domain().get() == diag->space().get()
this->this->range().get() == diag->space().get()

template<class Scalar >

void Thyra::DefaultDiagonalLinearOp< Scalar >::initialize ( const RCP< const VectorBase< Scalar > > & diag )

Initialize given a const diagonal vector.

Parameters

diag	[in] Smart pointer to diagonal vector.

Preconditions:

diag.get()!=NULL

Postconditions:

this->getNonconstDiag() with throw an exception if called
this->getDiag().get()==diag.get()
this->this->domain().get() == diag->space().get()
this->this->range().get() == diag->space().get()

Definition at line 81 of file Thyra_DefaultDiagonalLinearOp_def.hpp.

template<class Scalar >

void Thyra::DefaultDiagonalLinearOp< Scalar >::uninitialize ( )

Uninitialize.

Postconditions:

this->getNonconstDiag().get()==NULL
this->getDiag().get()==NULL
this->this->domain().get()==NULL
this->this->range().get()==NULL

Note: If the client wants to hold on to the underlying wrapped diagonal vector then they had better grab it using this->getDiag() or this->getNonconstDiag() before calling this function!
