Documentation

HCL_FunctionalProductDomainGrad_d represents a functional with gradient whose domain is a product space. In other words, an input to the functional represented by this class is naturally regarded as a vector with several components, each component belonging to a vector space.
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_ProductVectorSpace_d& ProductDomain()
Access to the domain, explicitly as a product vector space

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 void PartialGradient( const HCL_Vector_d & x, HCL_Vector_d & g, int i )
PartialGradient computes the gradient with respect to the ith component of the independent variable, at x. It does so by creating an evaluation object with the EvaluateGrad method, getting the partial gradient from it, and deleting the evaluation object. PartialGradient is defined in this (the base) class, so it need not be redefined in a derived class.

virtual ostream& Write( ostream & str )
