[petsc-users] PETSc recommended visualization packages

[Ethan Coon]

I suppose it's possible, eventually.  Much of the matlab stuff is
related to the socket and the "wrappers", which exist in petsc4py
instead.  There may be a few though -- PetscBinaryWrite.py at least.

For things run on a reasonably-sized problem, matplotlib (using either h5py to read hdf5, pyvtk to read vtk, or petsc4py to read PETSc's binary format) makes publishable plots.
