title: Get non normalized eigenvectors in scipy
body: <p>Scipy and Numpy returns eigenvectors normalized.  I am trying to use the vectors for a physical application and I need them to not be normalized.</p>
  
  <p>For example 
  <code>a = np.matrix('-3, 2; -1, 0')
  W,V = spl.eig(a)</code></p>
  
  <p>scipy returns eigenvalues (W) of <code>[-2,-1]</code> and the modal matrix (V) (eigenvalues as columns) <code>[[ 0.89442719  0.70710678][ 0.4472136   0.70710678]]</code></p>
  
  <p>I need the original modal matrix <code>[[2 1][1 1]]</code></p>
