Quiver arrow doesn't show at the right place

o = [0,0];
v = [3 10];
quiver(o(1), o(2), v(1), v(2),'k','LineWidth',2);
hold on
plot(v(1),v(2),"o")
xlim([(-1) (11)]);
ylim([(-1) (11)]);
grid on

The arrow is pointing towards [3, 10] but ends around [2.75, 9] while it should've stop at the red dot, right? Or am i wrong?

By default, AutoScale is set to on and AutoScaleFactor is 0.9.

So you may set AutoScale to off or set AutoScaleFactor to 1.

I can understand why an autoscalefactor option is usefull but why set it to 0.9 by default? Anyway thank you!
