title: Add "Appendix" before "A" in thesis TOC
body: <p>I am required to insert the word Appendix before the letter A in my dissertation Table of Contents as follows:</p>
  
  <p>Appendix A (title for appendix A)</p>
  
  <p>but the latex thesis cls file I use generates only the letter A followed by the appendix title: </p>
  
  <p>A (title for appendix A)</p>
  
  <p>The thesis cls file defines a "backmatter" command and the appendix is treated as a chapter. </p>
  
  <pre><code>\newcommand\backmatter{\appendix
  \def\chaptermark##1{\markboth{%
  \ifnum  \c@secnumdepth &gt; \m@ne  \@chapapp\ \thechapter:  \fi  ##1}{%
  \ifnum  \c@secnumdepth &gt; \m@ne  \@chapapp\ \thechapter:  \fi  ##1}}%
  \def\sectionmark##1{\relax}}
  </code></pre>
  
  <p>Is there a simple fix to the above code that will add the word Appendix before the letter A in the TOC for Appendix A?  There is a related question, <a href="https://stackoverflow.com/questions/717316/how-to-make-appendix-appear-in-toc-in-latex">How to make &#39;appendix&#39; appear in toc in Latex?</a>, but the answers did not appear to help in this case.</p>
