Hi There;
I should apply Backword integration for system of differential equation by ODE45 solver in Matlab, it seems easy for some people, I want an example to understand how to make Backword integration. your answer appreciated.

fun = @(t,y) y;
tspan = [0 1];
y0 = 1;
[Tf,Yf] = ode45(fun,tspan,y0);
tspan = [1 0];
y0 = exp(1);
[Tb,Yb] = ode45(fun,tspan,y0);
plot(Tf,Yf,Tb,Yb)

@Torsten already reported an example. I still warn you to pay attention to integrate backwards because in some cases you may have numerica blowup
