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.

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

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