title: How to convert a numeric variable to a string in MATLAB
body: <pre><code>A=rand(10)
  B=find(A&gt;98)
  </code></pre>
  
  <p>How do you have text saying "There were 2 elements found" where the 2 is general i.e. it isn't text, so that if I changed <code>B=find(A&gt;90)</code> it would automatically no longer be 2.</p>
