Hi

Thank you for the hint. MM format does the trick for me. In fact I try 
to look for something like MatView in Petsc:

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MatView.html

My matrix is in blocked structure and I want to inspect the magnitude 
among blocks. I hope this feature will be incorporated to Trilinos in 
the future.
