Hello all,
Actually, I am dealing with an issue that I can't get desirable results out of my curve-fitting problem. I used lsqcurvefit in the first place. Then, I added MultiStart to my code as well but my result didn't change. I don't know why MATLAB gives the unknown model coefficient (B in my problem) the same value as I entered for MATLAB. I have attached my code in the following along with the results. I would really appreciate it if someone can help me fix this problem and get better results:
