# DAGetLocalVector

Gets a Seq PETSc vector that may be used with the DAXXX routines.

### Synopsis

    #include "petscda.h"
    PetscErrorCode PETSCDM_DLLEXPORT DAGetLocalVector(DA da,Vec* g)

Not Collective

### Input Parameter

da -the distributed array

### Output Parameter

g -the local vector

### Note

The vector values are NOT initialized and may have garbage in them, so you may need to zero them.

The output parameter, g, is a regular PETSc vector that should be returned with DARestoreLocalVector() DO NOT call VecDestroy() on it.

VecStride*() operations can be useful when using DA with dof > 1

### Keywords

distributed array, create, local, vector
