9: VecCreateSeq - Creates a standard, sequential array-style vector.
11: Collective
13: Input Parameters:
14: + comm - the communicator, should be `PETSC_COMM_SELF`
15: - n - the vector length
17: Output Parameter:
18: . V - the vector
20: Level: intermediate
22: Notes:
23: Use `VecDuplicate()` or `VecDuplicateVecs()` to form additional vectors of the
24: same type as an existing vector.
