Regarding "interval mathematics", Wikipedia has an article,

        http://en.wikipedia.org/wiki/Interval_(mathematics)

Oscar, are you looking to do interval arithmetic?

        http://en.wikipedia.org/wiki/Interval_arithmetic

Via a quick Google, I found this toolbox

        http://www.ti3.tu-harburg.de/rump/intlab/

And a Matlab 5 version

        http://www.ti3.tu-harburg.de/zemke/b4m/

I took a quick look. My impression is that both should work in Octave.
