# VecCreateSeq
Creates a standard, sequential array-style vector. 
## Synopsis
```
#include "petscvec.h"   
PetscErrorCode VecCreateSeq(MPI_Comm comm, PetscInt n, Vec *v)
```
Collective


## Input Parameters

- ***comm -*** the communicator, should be `PETSC_COMM_SELF`
- ***n -*** the vector length



## Output Parameter

- ***V -*** the vector





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