A note about the documentation...

Several functions have been added to the package after completing the tutorial (April 2000). The on-line help files are more up-to-date. You can download them from above or browse them here The most up-to-date documentation is found in the help texts of the MATLAB functions themselves. Try, e.g.,

>>help somtoolbox

in MATLAB.

News and updates

There seems to be some problems with som_show visualization in the new Matlab 7.. The operation of MATLAB function subplot seem to have changed. We are not sure if we are able to correct this for a while.

Aug 7th 2003 / Mar 16th 2005

• som_fuzzycolor: a major bug with normalization corrected: now computes the contraction projection (and coloring properly!)
• som_dendrogram: a small bug with the user defined distance matrix corrected, a bug (v6.5 problem) corrected.
• som_kmeanscolor: help text corrected
• som_gui: a small, rarely occurring bug corrected
