Linear system partitioning

[Pierre Gay]

Hello,

I'm trying to use PETSc to partition and renumber a linear system. I
found some examples in the distribution:

$(PETSC_DIR)/ksp/ksp/examples/tutorials/ex10.c
$(PETSC_DIR)/mat/examples/tests/ex73.c

But these seem to only renumber the matrix. I also need to renumber
associated vectors (right hand side, solution) and I did not manage to
get some working code.

Could someone lead me to an example?

Many thanks,

Pierre
