title: Bold Greek letters in matlab latex interpreter
body: <p>I tried using bold font for the Greek letters in my axis labels in Matlab but they don't seem to work.</p>
  
  <p>For example:</p>
  
  <pre><code>xlabel('\mathbf{\rho}','Interpreter','latex')
  </code></pre>
  
  <p>I've tried other commands such as <code>\bf</code> but still it doesn't work.</p>
  
  <p>Does anyone know how to get around this?</p>
  
  <p>Thanks!</p>
