title: Calling C++ file from MATLAB
body: <p>I have a folder that implements the Shape Context descriptor, and it contains <code>.m</code> files and <code>.cpp</code> files. When some <code>.m</code> file calls a <code>.cpp</code> file, MATLAB yields: <code>??? Undefined function or method ‹The functions' name› for input arguments of type ‹double›.</code> although I have everything in path.</p>
  
  <p>Am I need to install something special in order to make MATLAB recognize this file?</p>
  
  <p>-Thanks</p>
