title: How to use libsvm in Matlab?
body: <p>I am new to matlab and don't know how to use libsvm. Is there any sample code for classifying some data (with 2 features) with a SVM and then visualize the result? How about with kernel (RBF, Polynomial, and Sigmoid )?
  I saw that readme file in libsvm package, but I could not make a head or tail of it would you please give an example of classification of 2 classes using Support Vector Machines (SVM) in matlab something like:</p>
  
  <pre><code>Attribute_1    Attribute_2   Class
  170            66            -1
  160            50            -1
  170            63            -1
  173            61            -1
  168            58            -1
  184            88            +1
  189            94            +1
  185            88            +1
  </code></pre>
  
  <p>Any help would be extremely appreciated.</p>
