Hi everyone I am having trouble fitting my data sets to a non-linear user defined function.
Here is the function that I want the data to fit to
Here lamba,delta, Amax, Amin can be determined so the actual parameters for fitting are alpha, beta, and gamma
This is what I expected the fitting function will do
This is what I actually get
Here is the raw data please help me out.
