PetscObjectStateSet#
Sets the state of any PetscObject, regardless of the type.
Synopsis#
#include "petscsys.h"    
PetscErrorCode PetscObjectStateSet(PetscObject obj, PetscObjectState state)
Logically Collective
Input Parameters#
- obj - any PETSc object, for example a - Vec,- Mator- KSP. This must be cast with a (- PetscObject), for example,- PetscObjectStateSet((- PetscObject)mat,state);
- state - the object state 
Note#
This function should be used with extreme caution. There is
essentially only one use for it: if the user calls Mat(Vec)GetRow(Array),
which increases the state, but does not alter the data, then this
routine can be used to reset the state.  Such a reset must be collective.
