Function/Subroutine Documentation
subroutine dladiv (double precisionA, double precisionB, double precisionC,
double precisionD, double precisionP, double precisionQ)
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:
