# PetscObjectStateSet

Sets the state of any PetscObject, regardless of the type.

### Synopsis

    #include "petscsys.h"
    PetscErrorCode PetscObjectStateSet(PetscObject obj,PetscObjectState state)

Logically Collective

### Input Parameter

| obj | - any PETSc object, for example a Vec, Mat or KSP. This must be cast with a (PetscObject), for example, PetscObjectStateSet((PetscObject)mat,state);
| state | - the object state

Notes: 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.
