uprod

unconstrained tool, form the matrix-vector product of a vector with the Hessian matrix

Calling Sequence

RESULT = uprod(X,P,goth)

Parameters

X

real vector, variables of the problem.

P

real vector required to perform the product with the Hessian.

goth

boolean, set goth to %t if Hessian has already been evaluated at the point X, %f otherwise. default: goth=%f.

RESULT

The result

Description

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.
