You have probably looked at different release versions for both
classes. We have renamed ConstraintMatrix to AffineConstraints (and made
ConstraintMatrix a type alias for AffineConstraints<double>).

The function make_periodicity_constraints will thus of course work with
AffineConstraints<double>.

Indeed it was my mistake, sorry :)
