Hi,
I need to have access to most of elements of a parallel MPIAIJ matrix only
from 1 process (rank 0).
I tried to copy or duplicate it to SEQAIJ, but I faced problems.
How can I have a local copy of a matrix which is distributed on multiple
process? I don't want to update the matrix, and the read-only version of it
would be enough.
Best,
Ehsan
