EzyFit Release Notes



See the EzyFit known software problems section.


V2.042006/09/07 New Frequently Asked Questions section.
Bug fixed: Selectfit now works when a legend box is present.
New options in fitparam: automakevarfit and whichpickdata.
fit, showfit and selectfit now also accept '!' and '$' instead of ';' to separate the list of options in the string FUN: this allows to use the syntax showfit power!log instead of showfit('power;log').
Minor bug fixed: showfit and selectfit now accept a fit structure F even if the original curve has been deleted.
New options in the item 'plotsample' of the Ezyfit menu.
V2.032006/04/12The 'EasyFit' toolbox has been renamed 'EzyFit', in order to avoid confusion with other products.
No change with EasyFit V2.02.
V2.022006/03/09Minor bugs fixed (the menus disappeared after a second call to plotsample; polynomial fits with unspecified orders was bugged).
'efmenu install' improved.
V2.012006/02/27Left-hand side now accepted for the fitting equation: fit('e(k)=c/k^n') specifies that 'k' stands for the X-Data.
Matlab's standard legends are now correctly supported.
The fitting equation is now case sensitive ('x' and 'X' are different).
Capital greek letters, and greek letters as subscripts, are now correctly interpreted in the equation boxes.
New functions evalfit, makevarfit and showresidual.
V2.002006/02/10Major changes for the functions fit, showfit and selectfit (free parameter names may now be used, eg, fit('a+c/x^n'), and new fit structure F).
New mat-files for predefined fits and user-defined fits.
New functions loadfit, editcoeff, showeqbox, dispeqfit.
Greek letters (lower case) are interpreted in the equation boxes (latex syntax).
Additional settings in fitparam.
Easyfit menu improved (Edit Fit Coefficients and Swap of the X- and Y- axis).
Better compatibility of the documentation with the Matlab help browser.
Function getfit retired (fit now does what getfit did).
V1.242006/01/30Bugs fixed in selectfit, drawpolygon and selectdata (better mouse button inquiries).
Bug fixed in efmenu (selectfit was wrong).
Showslope improved.
V1.232006/01/25User defined fits improved again (no need to type the fit number).

Now displays equations in Kaleidagraph or ABC mode.
V1.112005/10/31fit now computes the Pearson's correlation coefficient R.
n-th order polynomial fits added.
Initial guess may be defined within the fitting function string (as in Kaleidagraph).
New functions pickdata, undofit, rmfit, swx...
V1.102005/10/18Bug fixed for showfit.
New function selectfit, to select data by mouse in a polygon.
New function plotsample.
V1.052005/10/07New predefined fits (gaussian fits).
