Example of a discontinuous initial condition

${\displaystyle u(x,0)=\{\begin{array}{cc}1& 0.4\le x\le 0.6\\ 0& \text{ otherwise }\end{array}}$

applied to the illustration problem in the Lax–Friedrichs method article modified to have periodic boundary conditions; if ${\displaystyle a=1}$ the exact solution at time ${\displaystyle t=1}$ is identical to this initial condition.
