title: Python eigenvectors
body: <pre><code>eigenvalues, eigenvectors = linalg.eig(K)
  </code></pre>
  
  <p>How can I print just eigenvectors of <code>len(K)</code>. So if there is <code>K</code>, 2x2 matrix, I get 4 eigenvectors, how can I print just 2 of them if there is <code>len(K)=2</code>....</p>
  
  <p>Many thanks</p>
