I recently learned that you can patch delaunay triangles easily in one go by using the options `Faces` and `Vertices`, but for the voronoi polygons it isn't that straightforward because they have a variable amount of vertices/faces (stored in a cell array `c`).

So now I don't know if it's even possible, but can you patch all voronoi polygons without looping? And if so, is it more efficient (time) compared to looping?

      [v,c] = voronoin(X)
      for i = 1:length(c)
          if all(c{i}~=1)
              patch(v(c{i},1),v(c{i},2),RGB2(i,:)/256,'EdgeColor','none');
          end
      end
