title: Matrix contains values but still symbolic - Matlab
body: <p>I have a matrix that is outputted like this:  </p>
  
  <pre><code>maximums =
  
      [ -9.9043877608991468201413092380493, 426.34796945271797204125533010993]
      [  9.3758615553048990076305298649689, 441.87005169359418197397861057075]  
  </code></pre>
  
  <p>But when I try and run any commands on it, I get an error saying that this matrix is still symbolic. I don't understand since it's just numeric values. Is there anyway of making this matrix outputted used by normal functions of Matlab?</p>
  
  <p>To get this matrix, I did calculate derivatives of a symbolic equation and then evaluate. But I'd like to run functions on this output.
  Thanks!</p>
  
  <p>EDIT (Here's an example of the command/error):  </p>
  
  <pre><code>[maxValue, rowIdx] = max(maximums(:,2),[],2)
  
  Undefined function 'max' for input arguments of type 'sym'.
  </code></pre>
