title: Display struct fields without the mess
body: <p>I have a struct in Octave that contains some big arrays.</p>
  
  <p>I'd like to know the names of the fields in this struct without having to look at all these big arrays.</p>
  
  <p>For instance, if I have:</p>
  
  <pre><code>x.a=1;
  x.b=rand(3);
  x.c=1;
  </code></pre>
  
  <p>The obvious way to take a gander at the structure is as follows:</p>
  
  <pre><code>octave:12&gt; x
  x =
  
    scalar structure containing the fields:
  
      a =  1
      b =
  
         0.7195967   0.9026158   0.8946427   
         0.4647287   0.9561791   0.5932929   
         0.3013618   0.2243270   0.5308220   
  
      c =  1
  </code></pre>
  
  <p>In Matlab, this would appear as the more succinct:</p>
  
  <pre><code> &gt;&gt; x
   x = 
      a: 1
      b: [3x3 double]
      c: 1
  </code></pre>
  
  <p>How can I see the fields/field names without seeing all these big arrays?</p>
  
  <p>Is there a way to display a succinct overview (like Matlab's) inside Octave?</p>
  
  <p>Thanks!</p>
