title: Zero-dimensional numpy.ndarray : only element is a 2D array : how to access it?
body: <p>I have imported a Matlab *.mat file using scipy.io and trying to extract the 2D data from it. There are several arrays inside, and when I am trying to get them I got stuck at the last operation.</p>
  
  <p>The data looks like the image below. When I try to index it: <em>IndexError: too many indices for array</em></p>
  
  <p>I have googled to the point that it looks like a single valued tuple, where the only element is my array. This in principle must be indexable, but it doesn't work. The <em>type(data)</em> returns &lt;<em>class 'numpy.ndarray'</em>></p>
  
  <p>So the question is: how do I get my 2D array out of this data structure?</p>
  
  <pre><code>    data[0] # Doesn't work.
  </code></pre>
