# DMGetCoordinatesLocal

Gets a local vector with the coordinates associated with the `DM`.

## Synopsis

    #include "petscdm.h"
    PetscErrorCode DMGetCoordinatesLocal(DM dm, Vec *c)

Collective the first time it is called

## Input Parameter

- dm - the `DM`

## Output Parameter

- c - coordinate vector

## Notes

This is a borrowed reference, so the user should NOT destroy `c`

Each process has the local and ghost coordinates

For `DMDA`, in two and three dimensions coordinates are interlaced (x_0,y_0,x_1,y_1,…) and (x_0,y_0,z_0,x_1,y_1,z_1…)
