Sets the grid information for setting values into a matrix via MatSetStencil()

#include "petscmat.h" 
int MatSetStencil(Mat mat,int dim,int *dims,int *starts,int dof)

Not Collective

	mat	- the matrix
	dim	- dimension of the grid 1,2, or 3
	dims	- number of grid points in x, y, and z direction, including ghost points on your processor
	starts	- starting point of ghost nodes on your processor in x, y, and z direction
	dof	- number of degrees of freedom per node
