you have a procss, you do the expirement, get data. you choose a model for that proces. you have do find the parameters.
i need one method to be explained, the changed differential method for parameter finding. with the use of neldeal mead nonlinear regression fo optimization, and runge kutta for numerical solving of ODJ.
i have the algoritam in front of me and i just don't get it. what is it tha you do, and in what order to get the solutions, the parameters.
thnx

If you find inflection points in your data take them to be the roots. See how many inflection points are there and multiply all the (x minus(-) those points) together and you will get the equation of the system. The inflection points are the parameters of the system.
