title: Solving a matrix in MATLAB?
body: <p>How does one solve the (non-trivial) solution Ax = 0 for x in <a href="http://en.wikipedia.org/wiki/MATLAB" rel="noreferrer">MATLAB</a>?</p>
  
  <pre><code>A = matrix
  x = matrix trying to solve for
  </code></pre>
  
  <p>I've tried solve('A * x = 0', 'x')  but I only get 0 for an answer.</p>
