# MatColoringGetDistance
Gets the distance of the coloring 
## Synopsis
```
#include "petscmat.h"  
PetscErrorCode MatColoringGetDistance(MatColoring mc, PetscInt *dist)
```
Logically Collective


## Input Parameter

- ***mc -*** the `MatColoring` context



## Output Parameter

- ***dist -*** the current distance being used for the coloring.





## Note
The distance of the coloring denotes the minimum number
of edges in the graph induced by the matrix any two vertices
of the same color are.  Distance-1 colorings are the classical
coloring, where no two vertices of the same color are adjacent.
distance-2 colorings are useful for the computation of Jacobians.
