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
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. |
