Hi Yohan,
Since the strict inequalities will become obsolete, it seems that the 'shift.m' function (and sdpsettings 'shift' option) will become obsolete as well. Indeed, the operation applies only to strict inequalities. Since it is often useful to force all inequalities to be strict using the 'shift' option, could you think about modifying 'shift.m' so that it will apply to all inequalities?
