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?
I think I’ve found a solution. Matlab has implemented
symunits
in the symbolic toolbox and I’ve found the original? on Github. Hopefully it is compatible to GNU Octave.I downloaded it and tried to run it, but it gets stuck in a loop and I don’t know how it could be fixed:
error: max_recursion_depth exceeded error: called from baseUnitSystem <unknown>
it seems the problem is in the line
coreUnits = buildCoreUnits(u.baseUnitSystem);
in the file
u.m
, I think becauseu.baseUnitSystem
tries to “call itself”. I don’t know what this should be supposed to do, and have no idea on how to possibly fix it :(It seems that the implementation of
classdev
in Octave is unfortunately not complete enough yet.😒
