Details:

quiver3 will not display arrowheads for vectors which exist only in the z axis
(ex. <0, 0, 1>) despite set(vector, 'ShowArrowHead', 'on'). Every angle has
been checked. See attached images.

Code example:

X = xlabel("X");
Y = ylabel("Y");
Z = zlabel("Z");
axis([-1 1 -1 1 -1 1],'square');

hold on
vx = quiver3(0,0,0,1,0,0)
hold on
vy = quiver3(0,0,0,0,1,0)
hold on
vz = quiver3(0,0,0,0,0,1)


set([vx,vy,vz], 'Color', 'black');
set([vx,vy,vz], 'LineWidth', 4);
set([vx,vy,vz], 'ShowArrowHead', 'on');
grid on

view([45,30]);
