Hi,
I use LV 6.1 and I want to use the Levenberg-Marquardt algorithm to extract the best fit coefficients for the following equation:
Y =A*(X-B)^(1.7)
The data I input are X and Y (that I know) and I expect the vi to display A and B. I also input approximate values of A and B. It works perfectly well for Y=A*(X-B)^2 or for any integer but neither for (1,7), nor for 1.7 or (17/10).
Has anyone an idea how to use a decimal number as an exponent? Is there another vi I can us?
Any help appreciated,
Nicooo
