title: How does one calculate the probability of a multivariate Gaussian in Scipy?
body: <p>How does one calculate the probability of a multivariate Gaussian at point <code>x</code> in Scipy?</p>
  
  <p>I tried</p>
  
  <pre><code>    probability = multivariate_normal(x, mean, v)
  </code></pre>
  
  <p>where <code>x</code>, <code>mean</code>, <code>v</code> are all correctly sized vectors, but I get:</p>
  
  <pre><code>    probability = multivariate_normal(x, mean, v )
  TypeError: __call__() takes at most 3 arguments (4 given)
  </code></pre>
