Dear Sirs
It seems to me that the plot should be wrong because there are two rows of vectors pointing down, when everithing is positive. Is there a bug in the quiver plot function?
Sincerely
Manuel Cornejo

I have a problem too with quiver. Everything works well if you invert u and v. I'm checking right now.

It seems to me the problem is that you used matrix operations when you intended array operations. Try this instead:
u = y./sqrt(x.^2+y.^2);
v = x./sqrt(x.^2+y.^2);
