I tried to fit some data by exponent equation , but failed. There is only one parameter of the fitting equation, other parameters are nonthing. But other examples for fitting are fine. I don't know what happened? Some one said this is the problem of origin 8.0. Please help me about this problem.
You'd better provide more information. No clues we can get from your description. Please send email to our technical support team with sample data, fitting equation and your serial numbers.
