ODE45- How to pass parameters out

Hi, Can anyone tell me how I can pass parameters out of a ODE when they are not being calculated as part of the differential equation but are subsidiary values. Wha I want to do is write them out at the end of a successful timestep (i.e. not get the values calculated with trial time step sizes)?
Is there a clever way to use global to do this?

Why don't you just solve your ODE first, and then call the RHS function, modified to print out your parameters of interest, at the timestep values?

There is no reliable way to check inside the ODE function, if a step is a trial or accepted step. Function evaluations can be used to find event values also.
