04 Jul 2014 Schemaball Plot correlation matrix as a schemaball Author: Oleg Komarov

@Pascal
You can normalize your matrix. I left this aspect to the user, since she can choose how to re-map the matrix to an arbitrary interval.

14 May 2014 unzip file\s An extention of MATLAB's unzip, which allows to extract one or more specified files ... Author: Tal Pasi

I tweaked the function a bit and fixed a bug. It would be great to link this submission to github, so that I could contribute.

13 May 2014 LISTZIPCONTENTS Lists the contents of a zip file. Author: Bob Hamans

Tested on R2014a and lists contents without unzipping.

Couldn't be simpler.

12 May 2014 Levenshtein Distance Fast (MEX) C++ Computing the Levenstein distance between strings fast in matlab using external mex c++ code Author: Hanan Shteingart

Tested against other m-code implementations. It's more that two orders of magnitude faster.

However, it would be great if an .m file with the help was added.

26 Jan 2014 Fast or Accurate Moving Average (mex functions) Return the moving average of 2D matrix X, given a running window w Author: Francesco Pozzi

A loop is definitely a slow solution, but you can also use filter(), which is still significantly slower than fastmovav() but also significantly faster than the accurate version:

Y2 = filter(ones(1,w)/w,1,X);

04 Jul 2014 Schemaball Plot correlation matrix as a schemaball Author: Oleg Komarov Schulthess, Pascal

Absolutely fantastic.
But, I'd love a way to also input arbitrary matrices with arbitrary value ranges. Is there a way to do that?
