class HCL_RestrictedFunctional_d : public HCL_Functional_d

HCL_RestrictedFunctional_d is a concrete class which creates a new functional from a functional defined on a product space, by fixing all but one of the components of the independent variable

Inheritance:

Public Methods

	HCL_RestrictedFunctional_d ( HCL_FunctionalProductDomain_d * ff, const HCL_ProductVector_d & x, int i ) Usual constructor; just needs the underlying functional (defined on a product space) and the index of the free component of the independent variable
	HCL_RestrictedFunctional_d ( HCL_FunctionalProductDomain_d * ff, HCL_ProductVector_d * x, int i ) Usual constructor; just needs the underlying functional (defined on a product space) and the index of the free component of the independent variable
virtual HCL_VectorSpace_d&	Domain () const Domain space access
virtual HCL_EvaluateFunctional_d*	Evaluate ( const HCL_Vector_d & x ) const Evaluate creates an "evaluation" object, which knows how to compute the function value, gradient and Hessian at the given x
virtual ostream&	Write ( ostream & str ) const Debugging information

HCL_RestrictedFunctional_d( HCL_FunctionalProductDomain_d * ff, const HCL_ProductVector_d & x, int i )

Usual constructor; just needs the underlying functional (defined on a product space) and the index of the free component of the independent variable. (Creates a copy of the vector.)

HCL_RestrictedFunctional_d( HCL_FunctionalProductDomain_d * ff, HCL_ProductVector_d * x, int i )

Usual constructor; just needs the underlying functional (defined on a product space) and the index of the free component of the independent variable. (Copies the pointer to the vector.) Note that the ith component of x will be changed when the functional is evaluated.

virtual HCL_VectorSpace_d& Domain() const

Domain space access. Returns a reference to the HCL_VectorSpace_d which forms the domain of the functional.

virtual HCL_EvaluateFunctional_d* Evaluate( const HCL_Vector_d & x ) const

Evaluate creates an "evaluation" object, which knows how to compute the function value, gradient and Hessian at the given x

virtual ostream& Write( ostream & str ) const

Debugging information. Write must be implemented in derived classes, and should print a description of the object that will be useful for debugging.
