evaluate the values of the Hessian for the position corresponding to the sparsity structure of the Hessian of a given AMPL problem
val = ampl_eval_spst_w_val(asl, v)
the dual variables
a structure which handles the pointer to the problem
a vector of values of the Hessian evaluated at the positions corresponding to the sparsity structure of the Hessian
Evaluate the values of the Hessian for the position corresponding to the sparsity structure of the Jacobian of a given AMPL problem. The Hessian is evaluated at the last point given to ampl_evalf.
