[petsc-users] partition an MPIAIJ matrix

20 Feb 2012

      Dear PETSc Developers,

I have an MPIAIJ matrix, I want to use MatPartitioning functions to
repartition the matrix.
Before doing this, I need to do MatCreateMPIAdj to generate an Adj Mat.
Could you give me some hints about how to get "i" and "j" (
http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MatCreateMPI...)
from existing MPIAIJ matrix?

Thank you very much,
Yujie
