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.
