title: how to multiply 2 numpy array with different dimensions
body: <p>I try to multiply 2 matrix x,y with shape (41) and (41,6)
  as it is supposed to broadcast the single matrix to every arrow in the multi-dimensions </p>
  
  <p>I want to do it as :</p>
  
  <pre><code>x*y
  </code></pre>
  
  <p>but i get this error</p>
  
  <pre><code>ValueError: operands could not be broadcast together with shapes (41,6) (41,) 
  </code></pre>
  
  <p>Is there anything I miss here to make that possible ?</p>
