[petsc-users] Persistence of sparse matrices.

I would like to create a persistent sparse matrix.  PETSc's
MatCreateSeqAIJ appears to be a useful way to instantiate a sparse
matrix structure in memory
 I would like to be able to write the structure out to disk and reload
it during later runs so that I can grow it incrementally.  My project
makes use of HDF5 and that seems to be a feasible technology for
saving and loading the matrix.  Are routines for saving and loading a
sparse matrix already available or would I need to write my own?
