SYNOPSIS

Functions/Subroutines

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

real function sladiv2 (a, b, c, d, r, t)

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


 and can be found in the paper


 'A Robust Complex Division in Scilab'

Parameters



          A is REAL



          B is REAL



          C is REAL



          D is REAL


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



          P is REAL



          Q is REAL


          The scalars p and q in the above expression.
