PetscErrorCode VecTaggerComputeIS(VecTagger tagger, Vec vec, IS is[], PetscBool *listed)
Collective
Input Parameters#
tagger - the
VecTagger
contextvec - the vec to tag
Output Parameters#
is - a list of the indices tagged by the tagger, i.e., if the number of local indices will be n / bs, where n is
