[petsc-users] Question about MatGetRow

Hello,


By using MatGetRow, user can get vectors from local matrix (at each
process).

However, I need other process's row values.
So I have 2 questions.

1. Is there any function for getting arrays from other process's??

2. Or is there any function like matrix version of vecscattertoall??

Thanks,
Hyung Kim
