PetscDualSpaceCreateInteriorDataDefault

Create quadrature points by examining interior functionals and create the matrix mapping quadrature point values to interior dual space values

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceCreateInteriorDataDefault(PetscDualSpace sp, PetscQuadrature *intNodes, Mat *intMat)

sp -The dualspace

	intNodes	- A PetscQuadrature object containing all evaluation points needed to evaluate interior degrees of freedom
	intMat	- A matrix that computes dual space values from point values: size [spdim0 x (npoints * nc)], where spdim0 is the size of the constrained layout (PetscSectionGetConstrainStorageSize()) of the dual space section, npoints is the number of points in allNodes and nc is PetscDualSpaceGetNumComponents().
