[petsc-users] about MatLoad

[Yujie]

Dear PETSc Developers,

Now, I have an existing MPIAIJ mat (I can't change its local
dimension).  I have a data file for it. I need to use MatLoad to read
this file. However, MatLoad decides the local dimension of mat it
uses. This local dimension is different with that of my existing mat
when I read the file. Do you have any method to help me read this file
for the existing mat? thanks a lot.

Regards,
Yujie
