[petsc-users] Save matrix to binary file on sub directory

Thu Oct 2 12:02:32 CDT 2014

I am using the pets viewer and I want to save binary file to sub directory.

I tried to save file to the current directory and it work fine.

when I try to use file name like this "./xyz_dir/file_name" it doesn't work.
