Member Function Documentation

virtual void Aristos::HessVec::getValue ( const Vector &  x, const Vector &  l, const Vector &  s, Vector &  Hs  ) const

pure virtual

Returns Hessian-of-Lagrangian times vector product.

Parameters

x	[in] - Current SQP iterate vector.
l	[in] - The vector of Lagrange multipliers.
s	[in] - The vector to which the Hessian-of-Lagrangian operator is applied.
Hs	[out] - Resulting vector.

Returns

None.

Detailed Description:

Interface function that evaluates the vector obtained by applying the Hessian-of-Lagrangian operator to a vector. To be subclassed and implemented by the user.

Note

The Aristos::Vector input parameters can be recast into user-accessible quantities by using the following syntax (this is only one example):
Teuchos::RefCountPtr<const YourVectorClass> ex = (Teuchos::dyn_cast<Aristos::YourVectorAdapter>(const_cast<Aristos::Vector&>(x))).getVector();
