  Performs the following operation:<br>
  <br>
  c = c + &alpha; * a * b<sup>H</sup><br>
  c<sub>ij</sub> = c<sub>ij</sub> + &alpha; * &sum;<sub>k=1:n</sub> { a<sub>ik</sub> * b<sub>jk</sub>}
  </p>
  
  @param realAlpha Real component of scaling factor.
  @param imagAlpha Imaginary component of scaling factor.
  @param a The left matrix in the multiplication operation. Not modified.
  @param b The right matrix in the multiplication operation. Not modified.
  @param c Where the results of the operation are stored. Modified.
