title: Retrieve elements of a CV_32FC3 CvMat?
body: <p>I'm creating a CvMat structure by calling</p>
  
  <pre><code>cvCreateMat(1,1,CV_32FC3);
  </code></pre>
  
  <p>This structure is filled by a subsequent OpenCV function call and fills it with three values (as far as I understand it, this is a 1x1 array with an additional depth of 3).</p>
  
  <p>So how can I access these three values? A normal call to</p>
  
  <pre><code>CV_MAT_ELEM(myMat,float,0,0)
  </code></pre>
  
  <p>would not do the job since it expects only the arrays dimensions indices but not its depth. So how can I get these values?</p>
  
  <p>Thanks!</p>
