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

 25:   Not Collective

 27:   Level: developer

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

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