Function/Subroutine Documentation

  subroutine sladiv (real a, real b, real c, real d, real p, real q)

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
