I want to fit my experimental results into the following equation but I don't know how to do it as I don't know how to enter the equation ? Would someone give me some advices? Many Thanks
You will need to write your function as a valid C math equation.
In Origin 7.5, you can bring up the Tutorials from the Help menu and then look at Tutorial 11:, Nonlinear Curve Fitting and within that tutorial the section on Defining a New Fitting Function.
Note that with complex expressions, you can break them down into multiple lines with temporary variables for some of the bigger terms etc to make it easy to type and be more readable.
