Hello everyone.
I am having trouble finding the initial parameter for user defined non-linear fitting.
For the fitting equation I am using is
y=0.037685+0.034905*sin((4*pi)/(532*10^-9)*C*(-A*(exp(-x/A)-1)+B*(exp(-x/B)-1))+3.8605);
It is basically an exponential in a sin function where A,B, and C are the parameters.
Here is what my raw data looks like
Could anyone help me or tip me on getting the initial guess values for the parameters?
