title: Matlab: link to variable, not variable value
body: <p>It has been very difficult to use google, MATLAB documentation, I've spent a few hours, and I cannot learn how to</p>
  
  <pre><code>x = 1
  y = x
  x = 10
  y
  
  ans = 10
  </code></pre>
  
  <p>what happens instead is:</p>
  
  <pre><code>x = 1
  y = x
  x = 10
  y
  
  ans = 1
  </code></pre>
  
  <p>The value of x is stored into y. But I want to dynamically update the value of y to equal x.</p>
  
  <p>What operation do I use to do this?</p>
  
  <p>Thanks.M</p>
