Why can't I change the 'MaxHeadSize' property of a QUIVER handle using the SET command in MATLAB 7.10 (R2010a)?

I would like to change the 'MaxHeadSize' property of my QUIVER object by using the SET command as follows:

x = [1:10];

y = ones(1,length(x));

u = zeros(1,length(x));

v = y; 

q = quiver(x,y,u,v);

set(q, 'MaxHeadSize',0.5) ;

drawnow;

However, after I change the 'MaxHeadSize', there is no change to the arrow heads.

This is a bug with the 'MaxHeadSize' property of the QUIVER command in MATLAB 7.10 (R2010a). As a workaround, please set the 'MaxHeadSize' property directly in the QUIVER command itself.

x = [1:10];

y = ones(1,length(x));

u = zeros(1,length(x));

v = y; 

q = quiver(x,y,u,v,'MaxHeadSize',0.5)
