11 Jun 2013 CVAP: Cluster Validity Analysis Platform (cluster analysis and validation tool) supplying over 17 validity indices and 5 clustering algorithms based on GUI Author: Kaijun Wang Ilc, Nejc

Many thanks to the author for his valuable and useful contribution. However, I think there is a bug in the implementation of the Dunn's index.

I have compared results from CVAP with the Julian Ramos' implementation (http://www.mathworks.com/matlabcentral/fileexchange/27859) and also with R package clValid. Output values from clValid and Ramos' code are identical, whereas the CVAP results are not in an agreement with them. I think there are errors in computing the diameter of clusters and the shortest distance between clusters (function 'valid_sumsqures'). Please, consider revising this part of code.

I have the same problem as Praful. Function 'pamc' and 'daisyc' undefined for input arguments of type double.
Does anybody know how to resolve this?

I was trying to run the code, but it say that "Undefined function 'pamc' for input arguments of
type 'double'". Is it that the function 'pamc' is missing?

Thank You

As this was made for an older version of matlab, the pamc.dll is no longer valid.
To solve errors with the pamc function, download the latest mex files from here:

http://wis.kuleuven.be/stat/robust/LIBRA

32-bit win => pamc.mexw32
64-bit win => pamc.mexw64

Alternatively, 32-bit windows users can also try renaming the pamc.dll to pamc.mexw32 although this has not been tested.
