Solving an ODE backwards in time

| Can I solve an ODE backwards in time using built-in matlab functions
such as ode or DDE23? I.e., given a final condition x(T), can I solve
the "terminal value problem"?

I think you should just be able to write your time duration as
t=[0 -10]
This will be the time duration argument to something like ODE45. You will
still use the initial condition as before.
(Here I assumed you want to integrate for 10 seconds backwards).
