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...

31 Oct 2014 EzyFit 2.42 A free curve fitting toolbox for Matlab Author: Frederic Moisy Arkadiusz

Having some problems after upgrading Matlab to 2014b version. Following Olaf's sugegstions, some of the problems are solved (efmenu in figure), however still cannot do fit, returned error:

Error in pickdata (line 84)
x=co.XData;

Error in ezfit (line 210)
[x,y,h] = pickdata(fp);

Error in showfit (line 164)
f=ezfit(fun,varargin{2:end});

(The line numbers might have changed since I tried to investigate a bit the problem)

Anyone has seen the same issue ??

I suggest the following improvement: in the uimage.m file, when both X an Y are uneven, it is better to replace

for i=1:nx
for j=1:ny
indi = find(x<=xe(i));
indj = find(y<=ye(j));
ce(j,i) = c(indj(end), indi(end));
end
end

with

xi = zeros(nx,1);
yi = zeros(ny,1);
for i=1:nx
indi=find(x<=xe(i));
xi(i)=indi(end);
end
for j=1:ny
indj=find(y<=ye(j));
yi(j)=indj(end);
end
for i=1:nx
for j=1:ny
ce(j,i) = c(yi(j), xi(i));
end
end

Kind regards.

Excellent tool. Needed a quick bug fix in 2014b:

in efmenu.m, replace everything with set(0,.. with set(groot,.. and get(0,.. with get(groot,... Also fixed line 95:

should be

if ~isempty(get(groot,'CurrentFigure'))

Replace everything with set(0,.. with set(groot,.. and get(0,.. with get(groot,... in other files as well

Dear Matt,
thank you for your suggestion. In order to remove the necessity of functions 'row' and 'col', the line 'ce = ...' should read:

ce = interp2(x,y,c,xe(:),ye(:)','nearest');

I can confirm that the speed for plot creation is increased by a factor of almost 500!!

(Tested using MATLAB 2014a)
