Dear Razvan,
the definition of the coefficient R is given here: http://www.fast.u-psud.fr/ezyfit/html/ezfit.html

Dear Maxwell,
This is because different matrix indexing conventions are used in Matlab and PIVMat.
This point is explained here:
http://www.fast.u-psud.fr/pivmat/html/pivmat_data.html
see the section "Matrix indexing"
I hope this helps,
F.

To Nick:

Yes, the problem is fixed since July 2010.
See the function "remove_efmenu_fig.m".

Dear Joseph,
Thank you for your suggestion.
But please note that this issue has already been addressed: use the function remove_efmenu_fig (included in the toolbox since 2010) in order to remove the Ezyfit menu from a saved figure.

Oooooooh... I must admit that Bjorn Gustavsson is totally right. This submission actually mimick to behavior of pcolor. Thank you for your remark, and sorry for this false good idea...

20 Feb 2014 boxcount Fractal dimension using the 'box-counting' method for 1D, 2D and 3D sets Author: Frederic Moisy chancay, orlando

Hi
I am Working with this method
I need to calculate the fractal dimension of lesions in the Brain but this are very smalls, size of lesions is( 7x5x8 ) , and the result of FD in this lesions is around 1.4 to 2,2, and do not understand why this result, would know that should is 2-3.

15 Feb 2014 EzyFit 2.42 A free curve fitting toolbox for Matlab Author: Frederic Moisy Jonathan

Having trouble getting the Ezyfit option on my figures. The tool is function within matlab, but not appearing in an interactive way on my figures. Matlab 2013b... Any help appreciated!

for those of you who want to set a bound to the parameters, you may try the following patch:

fangq@wazu:~/space/Libraries/ezyfit$ diff ezfit.m.old ezfit.m
203a204
> bounds={};
240a242,244
> if nargin>4
> bounds={varargin{5:end}};
> end
548c552
< m=fminsearch(@fitlin, m0);
---
> m=fminsearchbnd(@fitlin, m0,bounds{:});
559c563
< m=fminsearch(@fitlog, m0); % bug fixed here! (v2.51)
---
> m=fminsearchbnd(@fitlog, m0,bounds{:}); % bug fixed here! (v2.51)

you will need to download the fminsearchbnd function from

http://www.mathworks.com/matlabcentral/fileexchange/8277-fminsearchbnd-fminsearchcon

and put the files under your matlab search path.

to set a bound, use

fitdata=ezfit(xdata,ydata,fun,p_ini,lb,ub);

where lb and ub are the lower/upper bounds, respectively, similar to those required by fminsearchbnd.

James, Sara, Thierry and all others:

R2013b doesn't have the start button anymore. To install, get your path to ezyfit (setpath) and save it in the Environment tab. Then there is a hard coded problem in efmenu.m at line 212. The semi-colon should be a colon:

212 sufolder = strrep(userpath,':','');
