28 Oct 2010 Label connected components in 2-D array LABEL is a generalization of BWLABEL Author: Damien Garcia

to Irwin Donis: Because LABEL works with arrays of any class, the 0s are NOT considered as the background. Only NaN values are considered as background. Transform your background into NaNs before using LABEL.

to Matthew: you should have read the File description:

07 Apr 2010 allwords Parse a sentence or any string into distinct "words" Author: John D'Errico

Valuable code, but I would suggest something as simple as:
words = regexp(str,'\w+','match')
which seems to be faster and could be easily adapted to the above-mentioned syntaxes.

As an example, try the following:
-----------------------------------
str = 'The quick brown fox jumped over the lazy dog.';
strlong = repmat(str,1,10000);
words1 = allwords(strlong);
words2 = regexp(strlong,'\w+','match');
isequal(words1,words2)
-----------------------------------

Regards, D.G.

25 Apr 2013 Image segmentation using Otsu thresholding OTSU(I,N) segments the image I into N classes by means of Otsu's N-thresholding method. Author: Damien Garcia Venkat

27 Mar 2013 Post-processing of PIV data PPPIV carries out robust & automated post-processing of 2-D PIV velocity data. Author: Damien Garcia arnold

can anyone give me an idea what I'm doing wrong? I'd really love this filtering ability!
06 Feb 2013 Post-processing of PIV data PPPIV carries out robust & automated post-processing of 2-D PIV velocity data. Author: Damien Garcia arnold

sounds interesting, but sadly doesn't work, not even the example. "pppiv" gives:
===========================
Error using smoothn
Too many output arguments.

Error in pppiv (line 152)
[V,s] = smoothn(V,s,'robust');

Error in pppiv>RunTheExample (line 227)
[Vx2,Vy2] = pppiv(Vx,Vy);

Error in pppiv (line 96)
if nargin==0&&nargout==0, RunTheExample, return, end
===========================

I have two row vectors with dx and dy data and I have many outliers. I'd be great if I could apply this for filtering.

thx
08 Nov 2012 Easy 'n fast smoothing for 1-D to N-D data SMOOTHN allows automatized and robust smoothing in arbitrary dimension w/wo missing values Author: Damien Garcia Michael

What is with the "DCTN and iDCTN are required"? I was able to access them outside the MatLab browser, but not from within it.
30 Oct 2012 Inpaint over missing data in N-D arrays Y = INPAINTN(X) replaces the missing data in X by extra/interpolating the non-missing elements. Author: Damien Garcia yo

hey everyone, the looks great, but unfotunately i've been getting the following error:

Error in ==> inpaintn at
140
y =
RF*idctn(Gamma.*dctn(W.*(x-y)+y))
+ (1-RF)*y;

since i don't feel capable enpugh changing the code on my own, can someone tell me what went wrong?

Thanks alot,

yoav
