title: Error: Undefined function or method 'svmtrain' for input arguments of type 'double'
body: <p>I am running</p>
  
  <pre><code>SVMStruct = svmtrain(xTrain, yTrain);
  </code></pre>
  
  <p>and the error I get is</p>
  
  <pre><code>Undefined function or method 'svmtrain' for input arguments of type 'double'
  </code></pre>
  
  <p>I am pretty sure xTrain and yTrain are matrices though:</p>
  
  <pre><code>size(xTrain)
  ans =
  544    28
  
  
  size(yTrain)
  ans =
  544     1
  </code></pre>
  
  <p>Any idea what's going on here?</p>
