It would help if you went into more detail.

What do you want to do with your system of differential equations?

Use a backwards linspace for generating "tspan" for one of the ODE integrators (e.g. ODE45).

For the forward direction, use something like tspan = 0:0.1:T. For the reverse direction, use something like tspan = T:(-0.1):0.
