title: Quiver plot without arrow stem
body: <p>I am simulating the motion of particles in MATLAB. I am using <code>quiver</code> to be able to get the direction of their motion. However, I would like to have only the arrowhead without the stem. I am unable to achieve this.</p>
  
  <p>I tried using the following,</p>
  
  <pre><code>quiver(x,y,vx,vy,'LineStyle','none','ShowArrowHead','on')
  </code></pre>
  
  <p>to get rid of the stem, but the arrowhead too does not show up. Is there a way around this?</p>
