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...

Dear Avanish, Jianan, Mohamed,
Thank you for your comments. I have posted a new version (PIVMat 2.01), which now fixes this issue. Now PIVMat is now compatible with the latest release of the ReadIMX package.
Frederic.

Dear Basim Kakakhel,
Please try the following: ezfit(c,y,'y(c)=a*(1-exp(-b*c)')

03 Jun 2010 DFT easy computation and display The program computes the DFT and displays it with the correct freq units and without the mirroring. Author: Javier Amezcua Frederic Moisy

Oh, it is exactly the same as EZFFT,

Dear Rahul,
Yes, just do the following
im = loadvec('B00001.im7');
hist(im.w(:),N); % N is the number of bins.
I hope this helps,
Fred.

30 Oct 2009 boxcount Fractal dimension using the 'box-counting' method for 1D, 2D and 3D sets Author: Frederic Moisy Frederic Moisy

Dear Marian
Please use my email address for questions or discussions about this submission. Algorithms to compute a fractal dimension (box-counting or other methods) are all approximations, which converge towards the "true" topological dimension in the limit of large scale separation. I hope this helps. - F.

29 Oct 2009 boxcount Fractal dimension using the 'box-counting' method for 1D, 2D and 3D sets Author: Frederic Moisy Frederic Moisy

Dear Marian,
What does it mean "the program crashes"? Please provide an example. If I make the simplefollowing test to compute the "fractal" dimension of a square,
a=zeros(4096,4096);
a(600:800, 1200:1400)=1;
boxcount(a,'slope')
it works properly (dimension close to 2 for small r, and close to 0 for large r, as expected)

Dear Andres,

Problem #1: This occurs if y and dy are column vectors instead of row vectors. If this is the case, then just replace [y; dy] by [y, dy]

Problem #2: Move the equation box using the mouse.

(Sorry for the unintentional rating of my own file on my previous post!)

TO UNINSTALL THE EZYFIT TOOLBOX:
1. Edit the 'startup.m' file (type 'edit startup') and remove the 2 lines starting with 'efmenu' and 'fprintf()'
2. Go the menu 'File', 'Set Path', and remove the directory 'ezyfit'
3. Restart Matlab

CONCERNING THE ISSUE OF THE EZYFIT MENU IN SAVED FIGURES AND GUIs:
Sorry for this bug, I have no idea on how to fix it. Suggestions are welcome. Note that you can use the Ezyfit toolbox without using the Ezyfit menu. For this, apply step 1 above.

Hope this helps - The author.
