04 Sep 2012 N-Puzzle (dynamic size and solver) Graphical User Interface for playing and solving the N-Puzzle game. Author: Per-Anders Ekstrom

06 Jun 2012 Tiedrank_(X,dim) Like MATLAB's tiedrank function, but works along dimension dim of ND-array. Author: Daniel

Very useful indeed! Thank you for that.
06 Jun 2012 Inequality Package Inequality Metrics: Gini Coefficient associated to the Lorenz Curve, Theil and Atkinson indexes Author: Francesco Pozzi

@Martin, thank you for your comment but check it again: the Gini coefficient of your example IS NOT zero but some random number.

@Robert, thank you for your comment - I would use random data or the GDP and Population of a selection of countries.

16 Aug 2011 logb Calculate the log of a number/matrix using a user-specified base. Author: Brett Shoelson

I had just written my own function and ... I've found yours. Trivial but handy - should be part of Matlab.

26 Aug 2010 Least Common Multiple Set Input a set of numbers as an n-dimension array, get their least common multiple. Author: Josh

I had the same problem and found your function. Thanks, Josh, very useful indeed.

16 May 2012 Inequality Package Inequality Metrics: Gini Coefficient associated to the Lorenz Curve, Theil and Atkinson indexes Author: Francesco Pozzi Root, Robert

Excited to find this package. I'd like to use it in my courses. Where can I find actual data in the format this package accepts?
31 Jan 2012 Rankings Calculate Rankings with five different methodologies Author: Francesco Pozzi Daniel

You might like my tiedrank_(X,dim) function: http://www.mathworks.com/matlabcentral/fileexchange/34560-tiedrankxdim
The code is fully vectorised and runs pretty fast.
