HCL_ALFcnlGrad_d( HCL_FunctionalGrad_d * ff, HCL_OpDerivAdj_d * GG, HCL_Vector_d * l, double rho=1.0, HCL_LinearOpAdj_d * SS=NULL )

Usual constructor.

virtual HCL_VectorSpace_d& Domain()

Domain space access.

virtual double MaxStep( const HCL_Vector_d & x, const HCL_Vector_d &dir)

MaxStep computes the longest vector from x in the direction dir that will lie in the domain of the functional, i.e. it computes the greatest $a$ such that $x + a*dir$ lies in the domain.

Table& Parameters()

Access to parameter table

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

I/O

virtual ostream& Write( ostream & str )

Write prints out some useful information about the function.
