# PetscQuadratureExpandComposite

Return a quadrature over the composite element, which has the original quadrature in each subelement

### Synopsis

    #include "petscdt.h"
    PetscErrorCode PetscQuadratureExpandComposite(PetscQuadrature q, PetscInt numSubelements, const PetscReal v0[], const PetscReal jac[], PetscQuadrature *qref)

Not collective

### Input Parameters

| q | - The original PetscQuadrature
| numSubelements | - The number of subelements the original element is divided into
| v0 | - An array of the initial points for each subelement
| jac | - An array of the Jacobian mappings from the reference to each subelement

### Output Parameters

| dim | - The dimension

Note: Together v0 and jac define an affine mapping from the original reference element to each subelement
