title: Matrix complex conjugate in OpenCV C++
body: <p>Does OpenCV provide any function to perform a matrix complex conjugate ?</p>
  
  <p>The only function I've found which might in a way do this, is the <code>void mulSpectrums(InputArray a, InputArray b, OutputArray c, int flags, bool conjB=false)</code> function.</p>
  
  <p>This is what the last argument does according to the doc:</p>
  
  <blockquote>
    <p>When the arrays are complex, they are simply multiplied (per element)
    with an optional conjugation of the second-array elements</p>
  </blockquote>
  
  <p>Isn't there a proper way of doing this for just one matrix, instead of having to multiply it, let's say, with an all-one matrix with the above function ?</p>
  
  <p>I'm trying to do a complex conjugate on a matrix on which I applied a DFT.</p>
