### Synopsis

    #include "petscmat.h"
    PetscErrorCode  MatPartitioningSetVertexWeights(MatPartitioning part,const PetscInt weights[])

Logically Collective on Partitioning

### Input Parameters

| part | - the partitioning context
| weights | - the weights, on each process this array must have the same size as the number of local rows
