30 Oct 2009	boxcount Fractal dimension using the 'box-counting' method for 1D, 2D and 3D sets Author: 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	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) F.
23 Oct 2009	EzyFit 2.30 A free curve fitting toolbox for Matlab Author: Frederic Moisy	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. -- The author
12 Dec 2008	EzyFit 2.30 A free curve fitting toolbox for Matlab Author: Frederic Moisy	(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.

22 Oct 2009	EzyFit 2.30 A free curve fitting toolbox for Matlab	Andres Klever	Hi Frederic, well im sending you this mail because i have a problem with this tool, first of all say to you thanks for this tool i think that is really good, ok , so there are 2 problems: 1) i have a problem with the weight In order to perform a weighted fit on this data, the vectors y and dy have to be merged into a 2-by-N matrix and given as the second input argument to ezfit. Compare the results for the usual and weighted fits: fw = ezfit(x, [y;dy], 'exp'); showfit(fw,'fitcolor','red'); f = ezfit(x, y, 'exp'); showfit(f,'fitcolor','blue'); my problem is that when i do this (exactly the same) the data [y;dy] is from a different size than x, so obiously i get this error: ??? Error using ==> ezfit at 272 X and Y dimensions must agree. if you can help me with this it would be great.. 2)the other problem is that when i plot more than one fit for the same data, the plot just shows one legend that is pasted into the other legend, hahaha, so i just can see one of the 2 legends that should appear (showing me the different equations)... ok, frederic sorry for asking you this questions but i really need to know this, thanks very much,	5
