WebThe primary differences are that FindFit: (1) recognizes EDA 's data format, including errors in both coordinates; (2) estimates errors in fit parameters; (3) by default displays graphical information about the fit; and (4) uses an algorithm that has been optimized for speed and stability for the types of nonlinear fits commonly performed in the … http://www.duoduokou.com/python/26635499544227499080.html

WebThis section also embodies computer codes. As mentioned, we have applied a Computer Algebra System (CAS), particularly Mathematica to carry out the needed symbolic and numeric computations. And hence, codes are crafted in Mathematica language. Interested readers may apply the codes producing our result.

If you can find a way to do that then maybe that is your solution. You can include constraints along with your equation in FindFit and you could try to use that to force each of the parameters into a range, but I'm not convinced. fell at workWebMathematica performs what is known as a least-squares fit of the data when applying the FindFit function.
