Detailed Description

Abstract Float simple Penta AOS flow.

Author:

Date:

Purpose:        Fast Computation of Simple Penta AOS recursive flow.
                        Use the Thomas LU model.
                        Semi-Implicit solver using AOS additive splitting

            (I - tau * A) * uNew=  uOld

                        Should be better than LOD: Rotation invariant.

                        LOD is sequential (handelling each direction x y z in sequence)

                        AOS is parallel (handelling each direction x y z at the same time)
                        AOS build an average operator

                        Both LOD and AOS are designed for large image restoration, O(N) in time ang space!!!
