Hello! In qalc I can do calculations using measuring units like this:
> 5 W * 3 s
(5 watts) × (3 seconds) = 15 J
I’d like to be able to do something similar also in GNU Octave. I think the symbolic library could be a place to look at, but I found nothing “already done”. Do any of you know of a way to achieve this functionality?

The Octave miscellaneous package has embedded GNU units as a function which should be helpful.
It looks interesting, but more focused on conversions than actual operations it seems:
octave:37> a.value = 100 a = scalar structure containing the fields: value = 100 unit = W octave:38> a.unit = 'W' a = scalar structure containing the fields: value = 100 unit = W octave:39> b.value = 3 b = scalar structure containing the fields: value = 3 unit = s octave:40> b.unit = 's' b = scalar structure containing the fields: value = 3 unit = s octave:41> a*b error: binary operator '*' not implemented for 'scalar struct' by 'scalar struct' operationsI think I’ve found a solution. Matlab has implemented
symunitsin the symbolic toolbox and I’ve found the original? on Github. Hopefully it is compatible to GNU Octave.This looks very VERY promising! I’ll try to install it tomorrow and Post here the results! Thanks?
