EzyFit Release Notes

# EzyFit Release Notes

See the EzyFit known software problems section.

V2.10 | 2006/10/30 | Major upgrade: Fit properties and display settings can now be passed to `showfit` and `selectfit`, such as fit colors, linewidth etc. For example: `showfit('power','fitlinewidth',2,'fitcolor','green')` The default properties are defined in `fitparam`. See the Settings page for details. New options in `fitparam`: `'selectfitloopmode'` and `'dispeqmode'`. Option `'eqdisplaymode'` renamed `'eqreplacemode'`. By default, the polygon procedure in `selectfit` is done once; set the option `selectfitloopmode` to 'on' to repeat the procedure until an empty polygon is drawn (as in the previous versions). `fit` now accepts row and column vectors for x and y. Minor bug fixed: `showfit` and `selectfit` now accept a fit structure F even if the original curve has been deleted. Minor bug fixed: when fitting histograms, the X points are now taken at the middle of the bins.
V2.04 | 2006/09/07 | 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.
V2.03 | 2006/04/12 | The 'EasyFit' toolbox has been renamed 'EzyFit', in order to avoid confusion with other products. No change with EasyFit V2.02.
V2.02 | 2006/03/09 | Minor bugs fixed (the menus disappeared after a second call to `plotsample`; polynomial fits with unspecified orders was bugged). '`efmenu install`' improved.
V2.01 | 2006/02/27 | Left-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`.
V2.00 | 2006/02/10 | Major 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).
V1.24 | 2006/01/30 | Bugs fixed in selectfit, drawpolygon and selectdata (better mouse button inquiries). Bug fixed in efmenu (selectfit was wrong). Showslope improved.
V1.23 | 2006/01/25 | User defined fits improved again (no need to type the fit number). Check when fitting negative data in log mode.
V1.22 | 2006/01/12 | User defined fits in the Easyfit menu improved.
V1.21 | 2005/12/21 | Documentation improved. New 'Known bugs' section. File 'Readme.txt' retired. selectfit improved (message boxes).
V1.20 | 2005/12/15 | EzyFit menu and dialog boxes included. Standard items for the toolbox in the Matlab 'Start' menu. New about, checkupdate. New home page (www.fast.u-psud.fr/ezyfit). drawpolygon improved..
V1.14 | 2005/12/03 | drawpolygon improved (interactive properties of the window suspended during the drawing).
V1.13 | 2005/11/25 | Bug fixed in myginput for Matlab >=7.0.0
V1.12 | 2005/11/03 | New parameter file 'paramfit.m'. New drawpolygon, and selectdata improved. getslope and showslope much better. Now displays equations in Kaleidagraph or ABC mode.
V1.11 | 2005/10/31 | fit 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...
V1.10 | 2005/10/18 | Bug fixed for showfit. New function selectfit, to select data by mouse in a polygon. New function plotsample.
V1.05 | 2005/10/07 | New predefined fits (gaussian fits). showfit now displays the equation in the plot. New file 'readme.txt'.
v1.04 | 2005/07/27
v1.00 | 2005/05/20 | First version. Originally called 'EasyFit toolbox'.
