Function/Subroutine Documentation

  subroutine sladiv (realA, realB, realC, realD, realP, realQ)

SLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

Purpose:

     SLADIV 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 REAL

    B

              B is REAL

    C

              C is REAL

    D

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

    P

              P is REAL

    Q

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