Inheritance:

Public Methods

	HCL_QuadFunctional_d ( HCL_LinearOp_d * a, HCL_Vector_d * bb = NULL, double aalpha=0.0 ) Usual constructor; takes a pointer to the linear operator, a pointer to the constant vector, and the constant scalar
virtual HCL_VectorSpace_d&	Domain () const Domain space access.
HCL_EvaluateFunctional_d*	Evaluate ( const HCL_Vector_d & x ) const Evaluate returns an evaluation object that can compute the function value, gradient, and Hessian
virtual ostream&	Write ( ostream & str ) const Write prints out some useful information about the object.
