Hy, for this plot

x = 2 :-0.25:0;
y = 0:0.25:2;
figure
compass(x,y)

For defaut the increment of theta is 30 degrees, please how i change it (15, 45 ...) for Matlab (R2009b)

Surprisingly enough, the plot created by compass is still a normal axis and not a polar axis. That means that there is no ThetaTick property. The quiver function cannot be used in a polar plot, so it would seem the only way to do it is to make your own function to draw arrows in a polar plot. You could also check if the arrow from annotation is to your liking.
