Detailed Description

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

A	input matrix (input)
permRowMap	Dof row map permutation shall be restricted on (input)
currentLevel	only for output of variables
genFactory	const 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.
