Documentation

HCL_LinearOpAdjInv_d represents a linear operator which knows how to compute both its adjoint and its inverse (or an approximation to it). The primary method, in addition to those of HCL_LinearOpAdj_d, is InvImage. If L is a HCL_LinearOpInvAdj_d, then 
   L.InvImage( y,x );
assigns to x the solution (perhaps approximate) of Lx=y.
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.

virtual void Image(const HCL_Vector_d & x, HCL_Vector_d & y)
Image computes the action of the operator on x, giving y.

virtual void AdjImage(const HCL_Vector_d & y, HCL_Vector_d & x)
AdjImage computes the action of the adjoint on y, giving x.

virtual void InvImage(const HCL_Vector_d & y, HCL_Vector_d & x)
InvImage computes the action of the inverse on y, giving x.

virtual void InvAdjImage(const HCL_Vector_d & x, HCL_Vector_d & y)
InvAdjImage computes the action of the inverse adjoint on x, giving y.

virtual ostream& Write( ostream & str )
Debugging information. Write should be implemented to print a description of the object that will be useful for debugging. If a complete description is lengthy, an implementor should consider just printing out a useful subset. This method will likely be used to send information to the screen when a error condition is encountered.
