Hi, I have a big problem with fitting (nonlinear). I have a table with my x/y values and created a plotted graph. I selected this function a opened the fitting menu.
I created my own, new user function for fitting. I added some parameters and the function.
After applying fitting and some parameters I get always the following output:
Iterations Performed = 0
Total Iterations in Session = 0
Fit did not converge - reason unknown.
Does anybody know, why my iterations are always 0 ???
Thanks for your help. |

Hi nora84,
I think there are varieties of possible reasons of the failure of fitting using your user-defined fitting function. It is hard to identify the cause based on what you wrote. I suggest you to contact OriginLab Technical Support, and send your FDF(Function Definition File) file of your function with your source data to them.
