title: How can I plot a 3D-plane in Matlab?
body: <p>I would like to plot a plane using a vector that I calculated from 3 points where:</p>
  
  <pre><code>pointA = [0,0,0];
  pointB = [-10,-20,10];
  pointC = [10,20,10];
  
  plane1 = cross(pointA-pointB, pointA-pointC)
  </code></pre>
  
  <p>How do I plot 'plane1' in 3D?</p>
