# PetscDualSpaceSimpleSetFunctional
Set the given basis functional for this dual space 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscDualSpaceSimpleSetFunctional(PetscDualSpace sp, PetscInt func, PetscQuadrature q)
```
Not Collective


## Input Parameters

- ***sp  -*** the `PetscDualSpace`
- ***func -*** the basis index
- ***q -*** the basis functional





## Note
The quadrature will be reweighted so that it has unit volume.
