15 Dec 2011 Random numbers from a user defined distribution creturns the matrix of random numbers from user defined probability density distribution. Author: Adam Nieslony

I wanted to do it, you already did it... perfectly. TY.

Hi Saif, I think all is ok except you maybe enter bad boundaries. I mean the boundaries you put do not allow the code to go toward the best parameters but to NAN. To handle that, you may simulate data. If again difficulties, please send me an email with the data, circuit, pinit and of course the LB/UB. Thanks.

Thank You !
For the reference, i suppose the author's name and the link to this page are sufficient.
25 Feb 2010 Waveform Generator GUI Generate waveformed signal and play it. Interactive GUI with movable datapoints. Author: Maxim Vedenyov

Amazingly good !

A GUI is now available, please see ZfitGUI :

http://www.mathworks.com/matlabcentral/fileexchange/26386-zfitguivarargin-fits-impedance-data

but still for MATLAB users because it is mandatory to write the fitting function. However, if no fitting is needed, checking the Z, Y, C or the Modulus spectra is easy...

Nice work

24 May 2010 ZfitGUI(varargin) fits and simulates impedance data ZfitGUI helps to identify a right model of complex data. Author: Jean-Luc Dellis Saif

Let me elaborate more:

When I write: ZfitGUI([zr',zi',fr']), a window pops up with my nyquist plot. I then choose "SelectLine" and click on the plot. I then go to "Circuit" and I input the circuit string and the vector "Pinit" which I think it works as an initial guess. I get a fitting curve (red) by clicking on "FIT". When I go to "Options" to set "LB/UB" variables and then click "FIT" again, I get an error:

Exiting: Maximum number of function evaluations has been exceeded
         - increase MaxFunEvals option.
         Current function value: NaN

Could you please help me with that?
Thanks.

Thank you for the great submission. How do I make the LB UB work?
