Detailed Description

template<class Scalar = double, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::LocalPermutationStrategy< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Local permutation strategy.

This class permutes columns of a input matrix A. No inter-node permutations are allowed, only permutations of columns that correspond to DOFs of the same node.

Member Function Documentation

◆ BuildPermutation()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void LocalPermutationStrategy::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.
