Detailed Description

A pure virtual interface for solving the transpose of a linear system.

virtual bool LOCA::Epetra::TransposeLinearSystem::AbstractStrategy::applyJacobianTransposeInverse ( Teuchos::ParameterList & params,

const NOX::Epetra::Vector & input,

NOX::Epetra::Vector & result

) [pure virtual]

Applies the inverse of the Jacobian matrix transpose to the given input vector and puts the answer in result.
Computes
$v = J^{-T} u,$
where $J$ is the Jacobian, $u$ is the input vector, and $v$ is the result vector.
The parameter list contains the linear solver options.
Implemented in LOCA::Epetra::TransposeLinearSystem::ExplicitTranspose, LOCA::Epetra::TransposeLinearSystem::LeftPreconditioning, and LOCA::Epetra::TransposeLinearSystem::TransposePreconditioner.
