MatZeroRows ignore negative indices?

[Pedro Juan Torres Lopez]

Hello,

In MatZeroRows() if I put negative value in the 3rd argument (rows[ ]) it
will be ignored?. I'm sorry if I'm being repetitive with this issue.

Regards

Pedro

MPE in PETSc

[Pedro Juan Torres Lopez]

Dear PETSc Team,

I'm trying to enable mpe log in PETSc. But compiling a example, I get this
errors,
/home/ptorres/soft/petsc-3.0.0-p5/src/ksp/ksp/examples/tutorials/ex23.c:38:
undefined reference to `PetscLogMPEBegin()'
/home/ptorres/soft/petsc-3.0.0-p5/src/ksp/ksp/examples/tutorials/ex23.c:193:
undefined reference to `PetscLogMPEDump(char const*)'

Do I need to define PETSC_HAVE_MPE in the installation step to fix that?. If
so, how can I do that?. I really appreciate any clue.
I send attached my 'make info' output.
Thanks in advance!.

Regards
