:orphan: # DMCompositeScatter Scatters from a global packed vector into its individual local vectors ## Synopsis ``` #include "petscdmcomposite.h" PetscErrorCode DMCompositeScatter(DM dm, Vec gvec, ...) ``` Collective ## Input Parameters - ***dm -*** the `DMCOMPOSITE` object - ***gvec -*** the global vector - ***Vec ... -*** the individual sequential vectors, NULL for those that are not needed ## Note `DMCompositeScatterArray()` is a non-variadic alternative that is often more convenient for library callers and is accessible from Fortran. ## See Also `DMCOMPOSITE`, `DM`, `DMDestroy()`, `DMCompositeAddDM()`, `DMCreateGlobalVector()`, `DMCompositeGather()`, `DMCompositeCreate()`, `DMCompositeGetISLocalToGlobalMappings()`, `DMCompositeGetAccess()`, `DMCompositeGetLocalVectors()`, `DMCompositeRestoreLocalVectors()`, `DMCompositeGetEntries()` `DMCompositeScatterArray()` ## Level advanced ## Location src/dm/impls/composite/pack.c ## Examples src/snes/tutorials/ex21.c
