Set values of symmetric matrices.

[billy at dem.uminho.pt]

Hi,

I use MatCreateMPIAIJ to create parallel matrices. I would like to use KSPCG to
solve a symmetric matrices. I tried to implement it but the program exits with
no error. Do I need only to set values on the diagonal and upper diagonal only
or continue to set all non-zero entries of the matrix?
