title: How to draw vectors (physical 2D/3D vectors) in MATLAB?
body: <p>I want to know the simplest way to plot vectors in <a href="http://en.wikipedia.org/wiki/MATLAB" rel="noreferrer">MATLAB</a>. 
  For example:</p>
  
  <pre><code>a = [2 3 5];
  b = [1 1 0];
  c = a + b;
  </code></pre>
  
  <p>I want to visualize this vector addition as head-to-tail/parallelogram method. How do I plot these vectors with an arrow-head?</p>
