#include "petscdmnetwork.h"  
PetscErrorCode DMNetworkVertexSetMatrix(DM dm,PetscInt p,Mat J[])

Not Collective

	dm	- The DMNetwork object
	p	- the vertex point
	J	- array of Jacobian (size = 2(num of supporting edges) + 1) submatrices for this vertex point: J[0]: this vertex J[1+2i]: i-th supporting edge J[1+2*i+1]: i-th connected vertex
