# BVSetRandomColumn

Set one column of a BV to random numbers.

### Synopsis

    #include "slepcbv.h"
    PetscErrorCode BVSetRandomColumn(BV bv,PetscInt j,PetscRandom rctx)

Logically Collective on BV

### Input Parameters

| bv | - basis vectors
| j | - column number to be set
| rctx | - the random number context, formed by PetscRandomCreate(), or NULL and it will create one internally.

### Note

This operation is analogue to VecSetRandom - the difference is that the generated random vector is the same irrespective of the size of the communicator (if all processes pass a PetscRandom context initialized with the same seed).
