title: Octave: Convert cell to matrix
body: <p>I am currently stuck on following: I would like to store the content of cells into a matrix of string ...</p>
  
  <p>I have the following cells:</p>
  
  <pre><code>words =     
  ans =     
  {    
    [1,1] = word1    
  }
  
  ans =     
  {
        [1,2] = word2    
  }
  </code></pre>
  
  <p>and I basically would like to get </p>
  
  <pre><code>words =    
  word1, word2
  </code></pre>
  
  <p>I am not entirely sure on how to do that ...</p>
