Description

An objective list contains an objective value, a gradient, and a Hessian matrix.

Objective lists can contain additional numeric attributes that are preserved or combined with the corresponding attributes of another objective list when both are added by the "+" operator, see sumobjlist.

Objective lists are returned by objective functions as being generated by normL2, constraintL2, priorL2 and datapointL2.
