Thanks. I don't have access or experience with Matlab so that seems not a good option. I'm fairly new to Python and have never done anything with the petsc python interface. But that could be an option. Once python reads in a petsc binary matrix, does it then have a function to write out the matrix in matrix market format? Or would I need to write the python code to do that?

Scipy has routines to write matrix market files. PETSc intentionally does not provide this routine because MatrixMarket is such a terrible format. We will give you the gun, but if you want to bolt it to your foot, you have to find your own bolts.
