This method solves a system of equations and returns the values of
the dependent variables at times or at \(t=0, dt, 2\;dt, ... Tmax\).
Arguments
- pars
a list that defines a model
- Tmax
the last time point, run from 0...Tmax
- dt
the time interval for outputs
- times
the times
Note
Note that xde_derivatives dispatches on class(frame)
