levenberg Marquardt: how to use a decimal as an exponent? it only works with integers!

[altenbach]

Are you sure the formula is A * [(B-x)^C]?

Do you have a link to the website that explains the experiment and the theory behind it?

For example, I would get a pretty good fit using A * [(x-B)^C]  with [A=19, B=5.2, C=0.7].

I'm sure the formula is a*[(x-b)^c], where c is a decimal. I'm glad to see that you succeeded with this formula but for me it never worked with a decimal as an exponent. Maybe it's because of my old version of labview (6.0, and no link to the website and the appropriate theory)
Nevertheless, I solved my problem as I explained in my last post.

Once again, thank you for all
