Thank you, I'll take a look in detail at those examples. However, those
examples don't use PETSc and the problem is that I can't find any method in
PETScWrappers::SparseMatrix to copy a matrix. Which way would you suggest?
Oh, I see, that is a problem. I think the simplest and most efficient way to
go about this is to see whether PETSc has the ability to copy its own
matrices, and then add a member function to the PETScWrappers::SparseMatrix
class that uses this functionality.
(It would of course be fantastic if this function then makes its way into
deal.II itself -- with which we'd be happy to help!)
