     12:   Input Parameters:
     13: + comm - the communicator, should be `PETSC_COMM_SELF`
     14: - n    - the vector length

     16:   Output Parameter:
     17: . v - the vector

     19:   Level: intermediate

     21:   Notes:
     22:   It is recommended to use `VecCreateFromOptions()` instead of this routine

     24:   Use `VecDuplicate()` or `VecDuplicateVecs()` to form additional vectors of the
     25:   same type as an existing vector.
