title: Adding a field to a structured numpy array (2)
body: <p>I know there was already a question about this topic (cleanest way to add a field to a structured numpy array), see </p>
  
  <p><a href="https://stackoverflow.com/questions/1201817/adding-a-field-to-a-structured-numpy-array">Adding a field to a structured numpy array</a></p>
  
  <p>but I have a question about the answer given there ...</p>
  
  <blockquote>
    <p>If you're using numpy 1.3, there's also numpy.lib.recfunctions.append_fields()</p>
  </blockquote>
  
  <p>I still have numpy 1.3, but it doesn't recognise this function, and I also didn't find anything about it in the documentation of numpy. What happened with the function? Is there another function that can do the same?</p>
