title: Element-wise minimum of multiple vectors in numpy
body: <p>I know that in numpy I can compute the element-wise minimum of two vectors with</p>
  
  <pre><code>numpy.minimum(v1, v2)
  </code></pre>
  
  <p>What if I have a list of vectors of equal dimension, <code>V = [v1, v2, v3, v4]</code> (but a list, not an array)? Taking <code>numpy.minimum(*V)</code> doesn't work. What's the preferred thing to do instead?</p>
