# PetscQuadratureSetData
Sets the data defining the quadrature 
## Synopsis
```
#include "petscdt.h" 
PetscErrorCode PetscQuadratureSetData(PetscQuadrature q, PetscInt dim, PetscInt Nc, PetscInt npoints, const PetscReal points[], const PetscReal weights[])
```
Not collective


## Input Parameters

- ***q  -*** The `PetscQuadrature` object
- ***dim -*** The spatial dimension
- ***Nc -*** The number of components
- ***npoints -*** The number of quadrature points
- ***points -*** The coordinates of each quadrature point
- ***weights -*** The weight of each quadrature point





## Note
This routine owns the references to points and weights, so they must be allocated using `PetscMalloc()` and the user should not free them.


## See Also
 `PetscQuadrature`, `PetscQuadratureCreate()`, `PetscQuadratureGetData()`

## Level
intermediate
