Detailed Description

Multi-step Jacobi preconditioner for linear systems.

NAME: PrecJacobiIter - Multi-step Jacobi preconditioner for linear systems

DESCRIPTION:

Solves the inner system by a fixed number of Jacobi iterations.

Constructor & Destructor Documentation

PrecJacobiIter::PrecJacobiIter ( const Precond_prm & p )

The only constructor accepts a "Precond_prm" object.

Member Function Documentation

String PrecJacobiIter::description ( ) const [virtual]

Reimplemented from Precond.

void PrecJacobiIter::init ( PrecBasis & Apb ) [virtual]

initializes the preconditioner, e.g. by computing an incomplete factorization. The function "init" should perform internal redimensioning if necessary. For algebraic preconditioners where C is based directly on A with the same sparsity pattern, C should be redimensioned by a "C.redim(A)" statement like we have for "LinEqVector" objects. The "Matrix"-heriarchy must then have a virtual makeItSimilar function (see "Vector"). Reimplemented from PrecItSolver.
