Question: Using dsolve to integrate numerically backward

Hello,

I am wondering if this is possible. I have a system of ODE that I want to solve numerically, let say they should give me x(t) and y(t) (two first-order ODE). But instead of specifying the initial condition as initial value: y(0) = a, x(0) = b, I want to specify the end value, e.g: x(10) = a, y(10) = b and let dsolve/numeric integrate backward from t=10 to t=1. Is it possible ? how do I do that ?

 

Thanks.
