title: MATLAB boxplot XTickLabel with subscripts
body: <pre><code>boxplot(rand(10,2))                     
  set(gca,'XTick',(1:2))
  set(gca,'XTickLabel',{'A_{a}','B_{b}'})  %a and b should be subscripts 
  </code></pre>
  
  <p>Does not plot a and b as subscripts as it is suppose to do. Any suggestion on how to make subscripts for XTickLabel?</p>
