# DMPlexGlobalToLocalBasis
Transform the values in the given local vector from the global basis to the local basis 
## Synopsis
```
#include "petscdmplex.h"   
PetscErrorCode DMPlexGlobalToLocalBasis(DM dm, Vec lv)
```

## Input Parameters

- ***dm -*** The `DM`
- ***lv -*** A local vector with values in the global basis



## Output Parameter

- ***lv -*** A local vector with values in the local basis





## Note
This method is only intended to be called inside `DMGlobalToLocal()`. It is unlikely that a user will have a local vector full of coefficients for the global basis unless they are reimplementing GlobalToLocal.
