class HCL_EvalLinCombFcnlGrad_d : public HCL_EvaluateFunctionalGrad_d

This class represents the "evaluation" object for HCL_LinCombFcnlGrad_d

Inheritance:

Public Methods

virtual HCL_VectorSpace_d&	Domain () Domain space access
virtual void	Gradient ( HCL_Vector_d & g ) Gradient computes the gradient of the function.
	HCL_EvalLinCombFcnlGrad_d ( HCL_VectorSpace_d * d, int n ) Usual constructor
void	SetNext ( HCL_EvaluateFunctionalGrad_d * eval, double w ) SetNext allows the next term in the linear combination to be added
virtual double	Value () Value computes the value of the function.
virtual ostream&	Write ( ostream & str ) Debugging information

HCL_EvalLinCombFcnlGrad_d( HCL_VectorSpace_d * d, int n )

Usual constructor. Takes the domain and the number of terms. Each of the terms in the linear combination, consisting of a scalar and a HCL_EvaluateFunctionalGrad_d, must be added with the SetNext method.

virtual HCL_VectorSpace_d& Domain()

Domain space access. Returns a reference to the domain of the functional, which is required to be a vector space.

virtual double Value()

Value computes the value of the function.

virtual void Gradient( HCL_Vector_d & g )

Gradient computes the gradient of the function.

void SetNext( HCL_EvaluateFunctionalGrad_d * eval, double w )

SetNext allows the next term in the linear combination to be added. This method takes the evaluation object and the weight.

virtual ostream& Write( ostream & str )

Debugging information. Prints out the weights and the individual evaluation objects.
