DMSlicedSetBlockFills

Sets the fill pattern in each block for a multi-component problem of the matrix returned by DMSlicedGetMatrix().

#include "petscdmsliced.h" 
PetscErrorCode  DMSlicedSetBlockFills(DM dm,const PetscInt *dfill,const PetscInt *ofill)

Logically Collective on dm

	sliced	- the DM object
	dfill	- the fill pattern in the diagonal block (may be NULL, means use dense block)
	ofill	- the fill pattern in the off-diagonal blocks

This only makes sense for multicomponent problems using scalar matrix formats (AIJ). See DMDASetBlockFills() for example usage.
