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
