HCL_EvalLSFcnlGNProductDomain_d( const HCL_ProductVector_d & Input, HCL_OpProductDomain_d * Operator, HCL_Vector_d * Data)

Usual constructor. The constructor requires (a reference to) the input vector and pointers to the operator and data. Note that an independent copy of the input vector is made.

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 PartialGradient( int i, HCL_Vector_d & g ) const

PartialGradient computes the component of the gradient corresponding to the ith component of the independent variable

virtual HCL_LinearOp_d* Hessian() const

Hessian computes the Hessian of the function. This method is re-defined in this class because, when the entire Hessian is desired, it can be provided more efficiently as the composition of the derivative and its adjoint, rather than as a block operator.

virtual HCL_LinearOp_d* HessianBlock( int i, int j ) const

HessianBlock creates the (i,j) block of the Hessian, as a linear operator

virtual ostream& Write( ostream & str ) const

Write invokes the Write method for the underlying objects (operator and data)
