Nonlinear curve fitting using labview

[altenbach]

This has very little resemblance to your code. I'll look at it later.

I won't be dissecting your formulas, but to get you started, here's a simple example how to fit it to an inverted Lorentzian. Maybe you can take it from here.... 😄

Sir,

I used the code which you sent. It was very help ful to me to understand the basics of fitting. I feel difficult to fit the data using the functions which I mentioned earlier. I don't know how to fit for the user defined functions. Could you please help me in this regard to solve the problem. Kindly suggest the way to get the solution. 

[altenbach]

Define "difficult".

Broken VI? Incorrect results? Slow convergence? ...?

I don't know how to create functions for user defined parameters.

I have fitting program using c language which I have attached. It requires orgin software to view and plot the results. Shall we try with this alogrithm in labview. In labview there is no need to use orign because in labview itself we will get plot. can you please look at the program and suggest whethere we can get the result by following this.

Could you please help me to solve..
