title: Is It Possible to Store cv::Point to cv::Mat?
body: <p>I want to store Points to an opencv matrix (cv::Mat), is it possible or not?
  I've tried it with this code:</p>
  
  <pre><code>cv::Mat_&lt;cv::Point&gt; matPoint;
  matPoint.at&lt;cv::Point&gt;(0) = cv::Point(2,2);
  std::cout &lt;&lt; matPoint.at&lt;cv::Point&gt;(0) &lt;&lt; std::endl;
  </code></pre>
  
  <p>Actually, it was compiled successfully, but when I run the code I got an "Floating point exception".
  I know my above code is wrong, but I don't know the other way to do it.</p>
  
  <p>Any help would be appreciated.
  Thank you</p>
