Use a VecTagger context to tag a set of indices based on a vector’s values

Synopsis

#include "petscvec.h" 
PetscErrorCode VecTaggerComputeIS(VecTagger tagger, Vec vec, IS *is, PetscBool *listed)

Collective

Input Parameters

• tagger - the VecTagger context

• vec - 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 VecGetLocalSize() and bs is VecTaggerGetBlockSize().

• listed - routine was able to compute the IS, pass in NULL if not needed
