easyfitGUI(varargin) fits real data Y = f(X)

easyfitGUI open a figure with uimenus devoted to process the data.

VARARGIN: one or several matrix [X, Y] having:
first column = vector of the independant variable (X)
second column = vector of the dependant variable (Y).
The Y-data are plotted versus the X-data.

for instance:






The available uimenus are :

Select the line to be fitted.
Move the Mouse to click on the targeted line.
The pointer gets a cross shape.
The selected line is redrawn with 'o' markers
The other lines remain with '.' markers

'express FIT' uimenu
The code uses POLYFIT. The sub menus offer the possibilities to fit with polynomials of degree 1 to 3. The "best" line is drawn in red. The "best" parameters are displayed in a message box. Uncertainties are output in the workspace.

'FUNCTION' uimenu
A input dialog is open to enter the name of the function which has to fit the data.
The user function used to model the data MUST HAVE the format (first line of the file):
'function y = myfun(p, x)'
where P is a vector of parameters, X the vector of the independant variable and Y is the dependant variable vector.
For instance:
function y = myfun(p, x)
computes a power law.

Define the initial values of the parameters before user-fitting.
Input commas or space-separated values without quotation marks nor brackets and whose the amount complies with the length of the vector p used by the fitting function.

'user FIT' uimenu
Here the GUI launches the function 'EASYFIT' which uses FMINSEARCH. The "best" line is drawn in red. The "best" parameters are displayed in a message box. Uncertainties are output in the workspace.

'OPTIONS' uimenu
It opens the following submenus:
* 'LB/UB' Gives the possibility to restrain the fitted parameters to a given domain or simply to fix some of them to a particular value. A input dialog is open to enter theses boundaries.
* 'Remove Outliers' activates the datacursor. A click on a point deletes the point. The outlier is covered by a grey marker.
Re-clik on the point to un-do the deletion. Disable the data cursor to end the 'remove outliers' tool.

'README' uimenu
It simply displays the help of easyfitGUI in the command window.

Zfit - Plots the impedance DATA which has to be a 3-columns wise matrix [FREQ, RealZEXP, ImagZEXP]

Fit experimental data is easy - pbest=EASYFIT(x,y,varargin) fits the data Y = f(X) to a model function Y = FUN(P,X). If FUN is not given as an input argument, POLYFIT is used as the model function. Bounds on the parameters P may be set.

ZfitGUI(varargin) fits and simulates impedance data - The main features are: Plot. For each immitance types (Z, Y, C or M), the data can be plotted in the complex plane, as well their real, imaginary parts or their magnitude in function of the frequency (Log/Log). Simulation.
