If we are to keep discussing this, and you continue to claim a factor
of ~5 difference in execution speed, then show us precisely the C code
and the Octave code you are comparing, and exactly how you ran the
comparisons, etc.

So what version of Octave were you using and how did you compile it
(compiler, version, options, OS, etc.)?

Exactly what C code did you use for comparision, and how did you
compile it?
