unconstrained tool, form the matrix-vector product of a vector with the Hessian matrix
RESULT = uprod(X,P,goth)
real vector, variables of the problem.
real vector required to perform the product with the Hessian.
boolean, set goth to %t if Hessian has already been evaluated at the point X, %f otherwise. default: goth=%f.
The result
uprod forms the product of a vector with the Hessian matrix of the objective function of the problem decoded into OUTSDIF.d at the point X in the case where the only possible constraints are bound constraints. If goth is omitted or set to 0, Hessian is not evaluated.
