DualLinearCombinationHessian¶
- class DualLinearCombinationHessian(*args)¶
Dual linear combination hessian implementation.
- Parameters:
- myDLCEI
DualLinearCombinationEvaluation
A dual linear combination evaluation implementation.
- myDLCEI
Notes
It returns the implementation of the hessian. By default, the analytical hessian is implemented.
Methods

Accessor to the object's name.
Accessor to the number of the inputs.
getMarginal
(*args)Accessor to the hessian implementation of a specific output.
getName
()Accessor to the object's name.
Accessor to the number of the outputs.
Accessor to the parameter values.
hasName
()Test if the object is named.
hessian
(inP)Return the Jacobian transposed matrix of the implementation at a point.
Accessor to the validity flag.
setName
(name)Accessor to the object's name.
setParameter
(parameter)Accessor to the parameter values.
