Description 
            Clustering Toolbox version 3.1
Copyright (c) by Dr. Eng. (J) Harald Galda, 2011

This toolbox implements functions for clustering and for evaluating clustering
algorithms.

The following functionality is provided:

1.  Random selection of row vectors from a matrix

2. Crisp clustering
- calculation of distances between sample vectors and cluster centers
- nearest neighbor search
- quantization error calculation
- c-means clustering
- Davies-Bouldin index

3. Fuzzy clustering
- fuzzy membership calculation
- fuzzy quantization error calculation
- fuzzy c-means clustering
- Xie-Beni index

4. Self organizing maps
- intialization with regular grid
- training
- mapping sample vectors to places on self organizing map

5. Visualization
- scatter plot of 2D principal component analysis

Changes between versions 3.1 and 3.0
- error in GetXieBeniIndex corrected

I believe there is an error in TrainSOM.sci.  The line
NeighborhoodFactor = Neighborhood(SOMDistances, n, LearningRateParameter)
seems to be wrong. probably supposed to be
NeighborhoodFactor = Neighborhood(SOMDistances, n, NeighborhoodParameter);

There may be afurther error.   The demo SOM.sce doesn't seem to work
correctly.  Repeating the call to trainsom with the updated weights,
gets a new answer after the first time, but from then on it is in a sort of loop.
