title: How to compute A^-1 x
body: <p>Using numpy, given a square matrix, A and column vector x, use np.linalg.solve to compute A^(−1)x.</p>
  
  <p>The documentation provides a simple example</p>
  
  <pre><code>&gt;&gt;&gt;a = np.array([[3,1], [1,2]])
  
  &gt;&gt;&gt;b = np.array([9,8])
  
  &gt;&gt;&gt;x = np.linalg.solve(a, b)
  
  &gt;&gt;&gt;x
  
  array([ 2.,  3.])
  </code></pre>
  
  <p>But I do not see how this problem relates and can be applied to the given problem to solve?</p>
