Hello,
I need to show a arrow of a vector (r, theta) form a point (x,y). Is there any function to do that?
Thanks for help.

x = rand
y = rand
r = rand
theta = 30; % Angle In Degrees
figure
quiver(x, y, r*cos(deg2rad(theta)), r*sin(deg2rad(theta)))
axis([0 2 0 2])
grid
Experiment to get different results.

You can make an arrow on a plot using the annotation function, or you may want to use a quiver plot if you want the arrow to come from the data itself.
