Hello,
I am currently trying to fit an experimentally determined PSD to a lorentzian curve using the Non-linear curve fit vi which uses the Levenberg-Marquardt algorithm.
I realize there have been several posts on this subject, but it is still unclear to me how to specify the function string (which blocks to use, syntax) and enter the experimentally obtained curve to fit to. I have attached a sample of the code and a picture of the curve I am trying to fit. Any advice would be greatly appreciated!
Thanks
