LabVIEW
exponential fitting
Hi there
I would like to make a program for fitting of one term exponential function base on the Levenberg-Marquardt algorithm in labview. I will use this program to extract phosphorescence lifetime. I have found Nonlinear Curve Fit VI module but the fitting does not look correct.
Indeed I appreciate if anyone knows how to improve the fitting or has a working example.
We all can look at the help and context help of the function, but we have no idea how your fit looks, what you expect, and why you think it looks incorrect.
Show us your code (caller and model) and some data instead of a picture of the function! Thanks!
(Note that there is also a direct function to fit single exponentials. If your data has an offset, make sure to relax the parameter bounds accordingly)
Also, if you want to dive a little deeper, have a look at my old group "Practical Nonlinear Fitting".
