title: NumPy linalg.eig
body: <p>I have this annoying problem and I haven't figured it out yet. I have a matrix and I want to find the eigenvectors, so I write:</p>
  
  <pre><code>val,vec = np.linalg.eig(mymatrix)
  </code></pre>
  
  <p>and then I got vec . My problem is when others from my group do the same with the same matrix (mymatrix) we dont get the same eigenvectors !!</p>
  
  <p>Someone who can put up an explanation? </p>
