title: Add brackets around a string
body: <p>I have a cell array of string like so.</p>
  
  <pre><code>'A' 'B' 'C'
  </code></pre>
  
  <p>I would like to add a bracket around each so it becomes:</p>
  
  <pre><code>'(A)' '(B)' '(C)'
  </code></pre>
  
  <p>I've tried the below where first_term_1 is A but that makes the its a 1x3 cell which is of no use to me. </p>
  
  <pre><code>new=['(' first_term_1 ')']
  </code></pre>
  
  <p>The whole point of this is for me to generate a simplified equation using a set of obtuse mathematical rules.</p>
