question about the quiver

I want to draw an arrow between to points like from (0,0) to (1,1). Should I use quiver? But when I use quiver(0,0,1,1), why is the end point (.9,.9)... Please help me, thanks~

Set the scale to zero:

quiver(0,0,1,1,0)
% .......scale ^

Sorry, I know it. Just put one more 0, like quiver(0,0,1,1,0), which means do not do the scaling automatically

Is that a further question?
