# DMLabelSetValue
Set the value a label assigns to a point. If the value is the same as the label's default value (which is initially -1, and can be changed with `DMLabelSetDefaultValue()` to something different), then this function will do nothing.
## Synopsis

#include "petscdmlabel.h"
#include "petscsection.h"
PetscErrorCode DMLabelSetValue(DMLabel label, PetscInt point, PetscInt value)
```
Not Collective
