# DMPlexLocalToGlobalBasis

Transform the values in the given local vector from the local basis to the global basis

## Synopsis

    #include "petscdmplex.h"
    PetscErrorCode DMPlexLocalToGlobalBasis(DM dm, Vec lv)

## Input Parameters

- dm - The `DM`

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

## Output Parameter

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

## Note

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