Purpose: Fast Computation of 2D Heat recursive flow. Splitted implicit solver using tridiagonals solvers when possible (I - tau/2 * Ax) * u$= [(I + tau/2 * Ay)] * uOld // X-sweep (I - tau/2 * Ay) * u= [(I + tau/2 * Ax)] * u$ // Y-sweep Papers: "Operator Splitting Techniques For Unsteady Navier Stokes Equations", Seongjai Kim, University of Kentucky, 2000. "Fractional Time Stepping Methods for Unsteady Flow Problems", Seongjai Kim & Jim Douglas, University of Kentucky, 2000. "Recursivity and PDE's in image processing", L. Alvarez, R. Deriche and F Santana, Spain 1998. "Numerical Receipes in C: Diffusion Equation in Multidimensions.", p666, William H. Press & all, Cambridge University Press, 1988. "Numerical Receipes in C: 17.6, Operator Splitting Methods and ADI.", p681-688, William H. Press & all, Cambridge University Press, 1988. Fast ADI_II (Kim 2000) is a DPR-ADI with splitting correction to "mimic the Cranck-Nicolson without error"
