title: Numpy zip function
body: <p>If I have two numpy 1D arrays, for example</p>
  
  <pre><code>x=np.array([1,2,3])
  y=np.array([11,22,33])
  </code></pre>
  
  <p>How can I zip these into Numpy 2D coordinates arrays?
  If I do:</p>
  
  <pre><code>x1,x2,x3=zip(*(x,y))
  </code></pre>
  
  <p>The results are of type list, not Numpy arrays. So I have do</p>
  
  <pre><code>x1=np.asarray(x1)
  </code></pre>
  
  <p>and so on..
  Is there a simpler method, where I do not need to call <code>np.asarray</code> on each coordinate?
  Is there a Numpy zip function that returns Numpy arrays?</p>
