Documentation

HCL_LNLOp_d creates a nonlinear op from a linear one. That is, it returns a nonlinear operator object (i.e. an instance of HCL_Op_d) which has precisely the same mapping behaviour as a linear operator (i.e. an instance of HCL_LinearOp_d). This is useful for instance in creating formally nonlinear least squares functions using HCL_LS_d (which can be fed to various nonlinear optimization algorithms),which are actually linear least squares functions.
HCL_LNLOp_d( const HCL_LinearOp_d * LL )
Usual constructor; just needs a pointer to the linear operator.

virtual HCL_VectorSpace_d& Domain() const
Domain space access. Returns a reference to an HCL_VectorSpace_d.

virtual HCL_VectorSpace_d& Range() const
Range space access. Returns a reference to an HCL_VectorSpace_d.

virtual HCL_EvaluateOp_d* Evaluate( const HCL_Vector_d & x ) const
Evaluate creates an evaluation object which knows how to compute the image, first derivative, and second derivative, along with all relevant adjoints, at a point. The purpose of the evaluation object is to accommodate the common situation in which the computation of the image and derivatives involve some common intermediate calculations.

virtual ostream& Write( ostream & str ) const
Debugging information.
