 21:   MatPartitioningRegisterAll - Registers all of the matrix Partitioning routines in PETSc.

 23:   Not Collective

 25:   Level: developer

 27:   Adding new methods:
 28:   To add a new method to the registry. Copy this routine and
 29:   modify it to incorporate a call to MatPartitioningRegister() for
 30:   the new method, after the current list.

 32:   Restricting the choices: To prevent all of the methods from being
 33:   registered and thus save memory, copy this routine and modify it to
 34:   register a zero, instead of the function name, for those methods you
 35:   do not wish to register.  Make sure that the replacement routine is
 36:   linked before libpetscmat.a.
