Detailed Description

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

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.
