class HCL_QuadRegFunctional_d : public HCL_FunctionalHess_d

HCL_QuadRegFunctional_d implements a quadratic functional defined by a linear operator A as follows: x |---> 0

Inheritance:

Public Methods

virtual HCL_VectorSpace_d& Domain ()
Domain space access.
HCL_EvaluateFunctionalHess_d* EvaluateHess ( const HCL_Vector_d & x )
EvaluateHess returns an evaluation object that can compute the function value, gradient, and Hessian

Public

constructors and destructor
HCL_QuadRegFunctional_d ()
Default constructor---disabled.
HCL_QuadRegFunctional_d ( const HCL_QuadRegFunctional_d & )
Copy constructor---disabled.
HCL_QuadRegFunctional_d ( HCL_LinearOp_d * a, HCL_Vector_d * bb = NULL )
Usual constructor; it just needs a pointer to the linear operator.
virtual ~HCL_QuadRegFunctional_d ()
Destructor.
I/O
virtual ostream& Write ( ostream & str )
Write prints out some useful information about the object.

Documentation

HCL_QuadRegFunctional_d implements a quadratic functional defined by a linear operator A as follows: x |---> 0.5*<x,Ax> + <b,x> The operator is assumed to be self-adjoint. The vector b is optional; if it is not provided to the constructor, it is assumed to be zero.
