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.
