title: how to do dividing between matrices?
body: <p>Today I encountered a piece of MATLAB code, which I can't understand well. It is</p>
  
  <pre><code>(Dpatch - min(Dpatch(:))) / (max(Dpatch(:)) - min(Dpatch(:)))
  </code></pre>
  
  <p><code>Dpatch</code> is a n*n matrix here. </p>
  
  <p>So what we will get after dividing a n*n matrix by a 1*n matrix ?</p>
  
  <p>Hoping for your help, thank you in advance.</p>
