Follow-up Comment #1, bug #52829 (project octave):

I think something more is wrong here.  It can't be the case that


A_lb <= A_in*x <= A_ub


Because A_lb and A_ub are matrices while the multiplication


A_in*x


is a vector.

I don't know how closely Octave follows Matlab's quadprog
(https://www.mathworks.com/help/optim/ug/quadprog.html), but they do not offer
the extra options A_lb, A_ub.
