title: How to set the plot in matlab to a specific size?
body: <p>Generally, I wish to plot a rather complex x-y plot (lots of overlapping curves) to an A3 format so:</p>
  
  <pre><code>A4 210x297  
  A3 = A4*2 = 420 x 297  
  ... - 10mm each side = 400 x 277 (size of desired plot window)
  </code></pre>
  
  <p>What is the easiest way to set the size of the plot so it fits that size when printed in PDF (or any other common output format)?</p>
