Zfit

ZFIT is a function which can PLOT, SIMULATE and FIT impedance data

Description

% Zfit(data)
Plots the impedance DATA which has to be a 3-columns wise matrix [FREQ, RealZEXP, ImagZEXP]. Impedance, admittance, capacitance and modulus representations in the complex plane are then pushbutton obtainable.

The others usages are described in the help lines with examples too...

Working just grate. Simple for operation by MATLAB user, but a GUI is needed for others. Very fast, and really converge to the data (not as the commercial programs which come with EIS systems).

[Jean-Luc Dellis]

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...

Excellent software, thanks. What should I make the reference to if writing a Journal Paper?

[Jean-Luc Dellis]

Thank You !
For the reference, i suppose the author's name and the link to this page are sufficient.
