Hybrid-norm and Fortran 2003: Separating the physics from the solver

Conclusions

Iterative-based inversion maps cleanly into an object-oriented framework. Vector, operator, and solver abstract classes can be built upon to solve nearly any inversion problem. The hybrid-norm approach requires some modification from the standard vector class description but can easily be accommodated. The Fortran 2003 standard contains all of the object-oriented features needed to write an inversion library.
