class HCL_ScaleLinearOp_d : public HCL_LinearOpNormal_d

HCL_ScaleLinearOp_d is a class implementing the linear operator mapping x to a*x, where a is a scalar

Inheritance:

Public Methods

virtual void	AdjImage ( const HCL_Vector_d & x, HCL_Vector_d & y ) AdjImage calls Image (the operator is self-adjoint).
virtual HCL_VectorSpace_d&	Domain () Domain space access
	HCL_ScaleLinearOp_d ( HCL_VectorSpace_d * SP, double mu ) Usual constructor; needs the domain and the scalar.
virtual void	Image ( const HCL_Vector_d & x, HCL_Vector_d & y ) Image computes y = a*x.
virtual void	NormalImage ( const HCL_Vector_d & x, HCL_Vector_d & y ) NormalImage computes $y = a^2x$.
Table&	Parameters () Access to the Parameter table
virtual HCL_VectorSpace_d&	Range () Range space access
virtual ostream&	Write ( ostream & str ) Write prints out the domain and scale.

HCL_ScaleLinearOp_d( HCL_VectorSpace_d * SP, double mu )

Usual constructor; needs the domain and the scalar.

virtual HCL_VectorSpace_d& Domain()

Domain space access. Returns a reference to the domain of the operator, which is a HCL_VectorSpace_d.

virtual HCL_VectorSpace_d& Range()

Range space access. Returns a reference to the range of the operator, which is a HCL_VectorSpace_d.

Table& Parameters()

Access to the Parameter table. The scalar defining the linear operator can be accessed through Parameters().GetValue( "Scale",val ) or changed by Parameters().PutValue( "Scale",val ).

virtual void Image( const HCL_Vector_d & x, HCL_Vector_d & y )

Image computes y = a*x.

virtual void AdjImage( const HCL_Vector_d & x, HCL_Vector_d & y )

AdjImage calls Image (the operator is self-adjoint).

virtual void NormalImage( const HCL_Vector_d & x, HCL_Vector_d & y )

NormalImage computes $y = a^2x$.

virtual ostream& Write( ostream & str )

Write prints out the domain and scale.
