unconstrained tool, evaluation of function and possibly gradient.
[F,G] = uofg(X)
real vector, variables of the problem
value of the objective function at the point X.
real vector, gradient of the objective function at the point X.
The uofg subroutine evaluates the value of the objective function of the current SIF problem (see usetup) at the point X, and possibly its gradient in the case where the only possible constraints are bound constraints.
