HCL_EvalLSFcnl_d(const HCL_Vector_d & Input, HCL_Op_d * Operator, HCL_Vector_d * Data, double PenaltyParameter, HCL_LinearOp_d * RegularizingOperator, HCL_Vector_d * ModelPrior)

Usual constructor. The constructor requires (a reference to) the input vector and pointers to the operator and data, and, optionally, a regularization weight, operator, and target model. Note that an independent copy of the input vector is made. See the documentation for HCL_LeastSquaresFcnl_d for more information about regularization.

virtual HCL_VectorSpace_d& Domain() const

Domain space access. Returns a reference to the vector space defining the domain of the functional.

virtual double Value() const

Value computes the value of the functional.

virtual void Gradient( HCL_Vector_d & g ) const

Gradient assigns to g the gradient of the functional.

virtual HCL_LinearOp_d* Hessian() const

Hessian creates the Hessian operator.

virtual ostream& Write( ostream & str ) const

Write invokes the Write methods of the operator and data.
