Summing up the ideas above,
we start from fitting goals

and we change variables from

Preconditioning means iteratively fitting
by adjusting the variables
and then finding the model by using
.A new reusable
preconditioned solver is
the module solver_prc .
Likewise the modeling operator is called Fop
and the smoothing operator is called Sop.
Details of the code are only slightly different from
the regularized solver
solver_reg .
