FD1D_ADVECTION_LAX_WENDROFF: MATLAB version Solve the constant-velocity advection equation in 1D, du/dt = - c du/dx over the interval: 0.0 <= x <= 1.0 with periodic boundary conditions, and with a given initial condition u(0,x) = (10x-4)^2 (6-10x)^2 for 0.4 <= x <= 0.6 = 0 elsewhere. We use the Lax-Wendroff method. Number of nodes NX = 101 Number of time steps NT = 1000 Constant velocity C = 1 CFL condition: dt (0.001) <= dx / c (0.01) FD1D_ADVECTION_LAX_WENDROFF Normal end of execution.
