# VecCreateSeqCUDA
Creates a standard, sequential, array-style vector. 
## Synopsis
```
#include <petscvec.h> 
PetscErrorCode VecCreateSeqCUDA(MPI_Comm comm, PetscInt n, Vec *v)
```
Collective, Possibly Synchronous


## Input Parameters

- ***comm -*** the communicator, must 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.

This function may initialize `PetscDevice`, which may incur a device synchronization.
