class HCL_RestrictedFunctionalGrad_d : public HCL_FunctionalGrad_d

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

Inheritance:

Public Methods

virtual HCL_VectorSpace_d&	Domain () Domain space access
virtual HCL_EvaluateFunctionalGrad_d*	EvaluateGrad ( const HCL_Vector_d & x ) EvaluateGrad creates an "evaluation" object, which knows how to compute the function value and gradient at the given x
	HCL_RestrictedFunctionalGrad_d ( HCL_FunctionalProductDomainGrad_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
	HCL_RestrictedFunctionalGrad_d ( HCL_FunctionalProductDomainGrad_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
virtual ostream&	Write ( ostream & str ) Debugging information

HCL_RestrictedFunctionalGrad_d( HCL_FunctionalProductDomainGrad_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_RestrictedFunctionalGrad_d( HCL_FunctionalProductDomainGrad_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.)

virtual HCL_VectorSpace_d& Domain()

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

virtual HCL_EvaluateFunctionalGrad_d* EvaluateGrad( const HCL_Vector_d & x )

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

virtual ostream& Write( ostream & str )
