2 difference eq sys quiver plot

Hi,

I just started using Matlab a few days ago, since I need it for my thesis. So maybe this is a fairly silly question but I can't really figure it out.


I would like to make a nice vector field for my system of two difference equations. However I'm not sure how to do this with the quiver plot. What I've done so far...looks kinda funky - code in the attachment.


Is there a better way? Or is the quiver function the wrong approach here?

Thanks.


P.S. If anyone reading knows some econ, I'm going for a phase diagram here!
