subroutine dladiv (double precision A, double precision B, double precision C, double precision D, double precision P, double precision Q)¶

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 is DOUBLE PRECISION

          B is DOUBLE PRECISION

          C is DOUBLE PRECISION

          D is DOUBLE PRECISION


          The scalars a, b, c, and d in the above expression.

          P is DOUBLE PRECISION

          Q is DOUBLE PRECISION


          The scalars p and q in the above expression.
