Purpose:        Fast Computation of 2D Heat recursive flow.

                AMOS implicit solver using 2D Pentadiagonal solvers
            (I - tau/2 * Ax) * u$=  (I + tau/2 * Ax) * uOld             // X-sweep
            (I - tau/2 * Ay) * u1=  (I + tau/2 * Ay) * u$               // Y-sweep

            (I - tau/2 * Ay) * u$=  (I + tau/2 * Ay) * uOld             // Y-sweep
            (I - tau/2 * Ax) * u2=  (I + tau/2 * Ax) * u$               // X-sweep

                 u= (u1+u2)/2                                                   // average sub-solutions
