title: How to prevent LATEX-labels in MATLAB GUI to become blurry?
body: <p>Within my current MATLAB GUI project, i have two axes objects. The first is used by the workaround <a href="http://www.mathworks.com/matlabcentral/fileexchange/10743-uibutton-gui-pushbuttons-with-better-labels" rel="nofollow noreferrer">"uibutton"</a> (I don't use GUIDE) in order to display a LaTeX-formula (as far as I know, only axes labels are capable to use LaTeX whereas normal static text fields aren't...). The other axes object is used to actually plot a 3D-function.</p>
  
  <p>The program has the following steps:</p>
  
  <ol>
  <li>the first axes creats the LATEX-formula (e.g. f(x)=).</li>
  <li>User enters a function in the edit field after the LaTeX-formula (e.g. f(x)=a+b).</li>
  <li>User presses a "plot"-button.</li>
  <li>3D-function is plotted in the second axes object.</li>
  </ol>
  
  <p>Problem:</p>
  
  <p>As soon as the 3D-function is plotted, the nicely rendered LaTeX-formular becomes crisp. Is there any way to prevent this from happening?</p>
