Function/Subroutine Documentation

   subroutine dladiv (double precisionA, double precisionB, double precisionC, double precisionD,
       double precisionP, double precisionQ)
       DLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

       Purpose:

            DLADIV performs complex division in  real arithmetic

                                  a + i*b
                       p + i*q = ---------
                                  c + i*d

            The algorithm is due to Michael Baudin and Robert L. Smith
            and can be found in the paper
            "A Robust Complex Division in Scilab"

       Parameters:
           A

                     A is DOUBLE PRECISION

           B

                     B is DOUBLE PRECISION

           C

                     C is DOUBLE PRECISION

           D

                     D is DOUBLE PRECISION
                     The scalars a, b, c, and d in the above expression.

           P

                     P is DOUBLE PRECISION

           Q

                     Q is DOUBLE PRECISION
                     The scalars p and q in the above expression.
