Hi @David Vatavu
It seems like you may have forgotten to attach the data using the paperclip icon . This sounds like a nonlinear system identification problem. If the generic mathematical model of the system is known or can be derived from the governing physical laws, then the identification task boils down to only estimating the coefficients of the system's ODEs to fit the given data using the lsqcurvefit() function.
Check out the example by @Star Strider.
