title: Python Median Filter for 1D numpy array
body: <p>I have a <code>numpy.array</code> with a dimension <code>dim_array</code>. I'm looking forward to obtain a median filter like <code>scipy.signal.medfilt(data, window_len)</code>. </p>
  
  <p>This in fact doesn't work with <code>numpy.array</code> may be because the dimension is <code>(dim_array, 1)</code> and not <code>(dim_array, )</code>.</p>
  
  <p>How to obtain such filter?</p>
  
  <p>Next, another question, how can I obtain other filter, i.e., min, max, mean?</p>
