title: How does subplot work and what is the difference between subplot(121) and subplot(1,2,1) in MATLAB?
body: <p>I am a bit unclear with how <code>subplot</code> works.  Specifically, what is the difference between <code>subplot(121)</code> and <code>subplot(1,2,1)</code> in MATLAB?  I have tried to search the <code>subplot</code> documentation, but I can't seem to find what I am looking for.</p>
