Out of curiosity, do you have concrete usage in mind?
That would be to gather 3 (always positive) indices of some gridpoint
(i,j,k)
What would be the return type of the difference operator between two
Vector3ui?
Indeed, I did not really think about it.. But in my mind, that would be
the job of Eigen (which seems to handle unsigned types [*] ?) to decide,
and I would just introduce a new typedef.
Actually my question came from the fear of falling under our recently
strengthened warning=error compilation policy, through possible signed
<-> unsigned conversions.
But I eventually did not face any of those in the meantime (while using
classical Vector3i and other unsigned int variables), so maybe there was
no point...
Thanks,
Jérôme

Hi,
It seems, in [*], we're not using typedef'd types for possible Eigen
Vector3<unsigned int>("Vector3ui" maybe).
Would you like / object to have one ?
