title: Difference between numpy.dot and a.dot(b)
body: <p>Is there a difference between</p>
  
  <pre><code>import numpy as np
  np.dot(a,b)
  </code></pre>
  
  <p>and</p>
  
  <pre><code>a.dot(b)
  </code></pre>
  
  <p>internally?
  I wasn't able to find any documentation on the latter method.</p>
