# MatPartitioningView
Prints the partitioning data structure. 
## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatPartitioningView(MatPartitioning part, PetscViewer viewer)
```
Collective on part


## Input Parameters

- ***part -*** the partitioning context
- ***viewer -*** optional visualization context





## Note
The available visualization contexts include

- ***`PETSC_VIEWER_STDOUT_SELF` -*** standard output (default)
- ***`PETSC_VIEWER_STDOUT_WORLD` -*** synchronized standard
output where only the first processor opens
the file.  All other processors send their
data to the first processor to print.


The user can open alternative visualization contexts with

- ***`PetscViewerASCIIOpen()` -*** output to a specified file
