Detailed Description

template<class Scalar = DefaultScalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::AlgebraicPermutationStrategy< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Algebraic permutation strategy.

This class permutes columns of a input matrix A trying to make A a diagonal dominant matrix.

◆ BuildPermutation()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void AlgebraicPermutationStrategy::BuildPermutation ( const Teuchos::RCP< Matrix > &  A,
const Teuchos::RCP< const Map > &  permRowMap,
Level currentLevel,
const FactoryBase genFactory 
) const

build permutation operators

The following variables produced "A" : permuted and scaled A "permA" : permuted A without scaling "permP" : permutation opertor (should be identity) "permQT": transpose permutation operators "permScaling": scaling operator

Parameters
Ainput matrix (input)
permRowMapDof row map permutation shall be restricted on (input)
currentLevelonly for output of variables
genFactoryconst pointer to generating (calling) PermutationFactory TODO avoid this, not very elegant. Decide which variables have to be generated, give them back per reference to the PermutationFactory.
