No graph appeared, but consider using the quiver function.

The graph is there, the quiver is no suitable

Now that I see what you want to do, consider using the annotation object, particularly the 'arrow' option. See the Annotation Arrow Properties for details. It would seem to do what you want.

When i add this comment

h=annotation('arrow',[.45 .55],[.45 .55]); c = h.Color; h.Color = 'r';

This error come out

"Attempt to reference field of non-structure array."

The current online documentation is for R2014b. If you have an earlier version, use the set funciton:

h=annotation('arrow',[.45 .55],[.45 .55]);
set(h, 'Color','r')

This worked for me when I tried it. (I have R2014b, so the structure reference also worked when I ran it.)
