The right way to do this is to input the matrix using MatSetValues()
in a distribute fashion. You can consult any of the tutorials, for instance
KSP ex2 for an example of this.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
