title: How to control the margin size around subplots?
body: <p>I'm plotting 5 x 3 plots using subplot command, but there are massive margins around each subplot. </p>
  
  <p>How do I control the margin size around them?</p>
  
  <pre><code>figure;
  for c=1:15
      subplot(5,3,c); 
      imagesc(reshape(image(:,c), 360,480)); 
      colormap gray; 
      axis image;
  end
  </code></pre>
