# PetscFEPushforwardGradient
Map the reference element function gradient to real space 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscFEPushforwardGradient(PetscFE fe, PetscFEGeom *fegeom, PetscInt Nv, PetscScalar vals[])
```

## Input Parameters

- ***fe     -*** The `PetscFE`
- ***fegeom -*** The cell geometry
- ***Nv     -*** The number of function gradient values
- ***vals   -*** The function gradient values



## Output Parameter

- ***vals   -*** The transformed function gradient values





## Notes
This just forwards the call onto `PetscDualSpacePushforwardGradient()`.

It only handles transformations when the embedding dimension of the geometry in fegeom is the same as the reference dimension.
