Did you look at the shipping examples?
Do you have reasonable guesses for F0 and alpha?
Do you have a link explaining the mathematical model?

Dear Altenbach,
I have looked for solution of my problem since yesterday. I've read description of nonlinear fitting, but I couldn't understand how it can count the values of my various F0 and Alfa.
Please, sorry for my elementary questions, but for me it is fussy...

You did not answer my earlier questions.

Yes, I've looked for examples, where as I understood was processing data fitting...
The values of F0 and Alfa must be near 10E+5 and 10E+7...
What mathematical model did you mean?

What about using Nonlinear System Single Solution.vi ??????

That might work too, but I have not tried.
Are you sure your system has a solution? A unique solution?
I was asking about a website explaining the mathematical model, because I suspect that your formula is not right.

Hi
You had a question about using Nonlinear Curve Fit.vi You can find examples that use the Nonlinear Curve Fit.vi here. If you navigate to the bottom of the help document you will see where to find the examples.
Hopefully you can tweak an example to work for you equation.

Hi all.
There is no website explaining my mathematical model. I'm doing research by myself... To my mind, ther is a solution (but I'm not sure).
According to the examples, I've looked them, but I have no ideas how I can find F0 and Alfa. Please, show me the way. I'm very hopeless now...
Thanks so much for your patience and help!!!!!!

If you are running into actual mathematical model problems you might want to use a site such as WolframAlpha to find further help.
