#include "petscis.h" int ISInvertPermutation(IS is,int nlocal,IS *isout)Collective on IS
| is | - the index set | |
| nlocal | - number of indices on this processor in result (ignored for 1 proccessor) or use PETSC_DECIDE |
Notes: For parallel index sets this does the complete parallel permutation, but the code is not efficient for huge index sets (10,000,000 indices).
