:orphan: # DMCreateLocalVector Creates a local vector from a `DM` object. ## Synopsis ``` #include "petscdm.h" #include "petscdmlabel.h" #include "petscds.h" PetscErrorCode DMCreateLocalVector(DM dm, Vec *vec) ``` Not Collective ## Input Parameter - ***dm -*** the `DM` object ## Output Parameter - ***vec -*** the local vector ## Note A local vector usually has ghost locations that contain values that are owned by different MPI ranks. A global vector has no ghost locations. ## See Also [](ch_dmbase), `DM`, `Vec`, `DMCreateGlobalVector()`, `DMGetLocalVector()`, `DMDestroy()`, `DMView()`, `DMCreateInterpolation()`, `DMCreateColoring()`, `DMCreateMatrix()` `DMGlobalToLocalBegin()`, `DMGlobalToLocalEnd()` ## Level beginner ## Location src/dm/interface/dm.c ## Examples src/dm/field/tutorials/ex1.c
