The main features are:
Graphical.
The data can be plotted for each immitance types (Z, Y, C or M), in the complex plane, as well as their real, imaginary parts or their magnitude in function of the frequency (Log/Log scales).
Simulation.
The possibilities are almost infinite. Over the classical R, C, L electrical elements, one can use CPE (constant Phase Element) and Diffusion Impedances.
Fitting.
ZfitGUI makes use of the simplex algorithm. To fit only portion of the spectra is user-friendly. Note that there exists the programmatic version of ZfitGUI named "Zfit" which can be found in the Matworks site file exchange.

Version Published Release Notes
1.0.4

Now the operators “s” and “p” may handle more than 2 elements as arguments. For instance the string “p(R1,E2,C1,E2)” with 4 impedances in parallel is allowed (code offered by Hazrul Shabri).

1.0.3

Wrong function name was corrected

1.0.2

- an uicontrol list type is now used to load and check impedance data from the Workspace;
- the hints on “How to” are displayed on the figure.
