If you think there is a bug in Octave, then please send a *complete*
bug report to the address@hidden list. If you're not sure what to
include in the report so that someone might actually be able to help
you solve the problem, then please read
http://www.octave.org/bugs.html before sending your report.
It seems unlikely to me that anyone will be able to help you if you
if all you provide is a complaint about performance and a vague
description of your code.
