Follow-up Comment #2:
ok sorry, the large data block didn't render properly on my screen at first.
I see now that you've copy/pasted the whole octave data session and results.
It seems you are concerned with the result
6.661338147750939e-16
not being exactly zero. Octave is a numerical computation tool using floating
point arithmetic. the numerical precision of any calculation is a complicated
affair, but it can be compared with the floating point relative accuracy,
"eps".
>> eps
ans = 2.2204e-16
what you have in that line is on the order of zero, within limits of floating
point accuracy. (it's about 3 eps). while it's possible for some
calculations 3eps would represents an inordinate amount of error i don't think
that is the case here.

closing as invalid.
