title: Matlab convert struct to cell array of strings
body: <p>I want to convert a structure to a cell array where all the entries are converted to strings, including numbers. If I take the MATLAB example:</p>
  
  <pre><code>s = 
      category: 'tree'
        height: 37.4000
          name: 'birch'
  </code></pre>
  
  <p>I want to convert this to </p>
  
  <pre><code>c = 
      'tree'
      '37.4000'
      'birch'
  </code></pre>
  
  <p>where all entries are converted to strings, including numbers. The function struct2cell(s) will convert s to:</p>
  
  <pre><code>ans =
      'tree'
      [37.4000]
      'birch'
  </code></pre>
  
  <p>Is there a quick way of getting from s to c?</p>
