title: Multi-class classification in libsvm
body: <p>I'm working with <a href="http://www.csie.ntu.edu.tw/~cjlin/libsvm/" rel="noreferrer">libsvm</a> and I must implement the classification for multiclasses with <em>one versus all</em>. </p>
  
  <p>How can I do it?<br>
  Does <code>libsvm</code> version 2011 use this?</p>
  
  <hr>
  
  <p>I think that my question is not very clear.
  if libsvm don't use automatically one versus all,I will use one svm for every class, else how can i defined this parameters in the <code>svmtrain</code> function.
  I had read README of libsvm. </p>
