Detailed Description

This class applies an operator as a smoother. The main idea being that a residual is used and corrected to get a Gauss-Seidel like method.

Member Function Documentation

virtual VectorSpace Teko::SmootherLinearOp::range ( ) const [inline, virtual]

Range space of this operator.

Implements Teko::ImplicitLinearOp.

Definition at line 67 of file Teko_SmootherPreconditionerFactory.hpp.

virtual VectorSpace Teko::SmootherLinearOp::domain ( ) const [inline, virtual]

Domain space of this operator.

Implements Teko::ImplicitLinearOp.

Definition at line 71 of file Teko_SmootherPreconditionerFactory.hpp.

void Teko::SmootherLinearOp::implicitApply ( const MultiVector &  x,
MultiVector &  y,
const double  alpha = 1.0,
const double  beta = 0.0 
) const [virtual]

Perform a matrix vector multiply with this implicitly defined blocked operator.

The apply function takes one vector as input and applies a linear operator. The result is returned in $y$. If this operator is reprsented as $M$ then $ y = \alpha M x + \beta y $

Parameters:
[in]x
[in,out]y
[in]alpha(default=1)
[in]beta(default=0)

Implements Teko::ImplicitLinearOp.

Definition at line 86 of file Teko_SmootherPreconditionerFactory.cpp.

void Teko::SmootherLinearOp::setRequestHandler ( const Teuchos::RCP< RequestHandler > &  rh) [virtual]

Set the request handler with pointers to the appropriate callbacks.

Implements Teko::RequestHandlerContainer.

Definition at line 130 of file Teko_SmootherPreconditionerFactory.cpp.

Teuchos::RCP< RequestHandler > Teko::SmootherLinearOp::getRequestHandler ( ) const [virtual]

Get the request handler with pointers to the appropriate callbacks.

Implements Teko::RequestHandlerContainer.
