# MatPartitioning

Object for managing the partitioning of a matrix or graph

## Synopsis

    typedef struct _p_MatPartitioning *MatPartitioning;

## Note

There is also a `PetscPartitioner` object that provides the same functionality. It can utilize the `MatPartitioning` operations via `PetscPartitionerSetType`(p,`PETSCPARTITIONERMATPARTITIONING`)

## Developer Note

It is an extra maintenance and documentation cost to have two objects with the same functionality. `PetscPartitioner` should be removed

## See Also
