from S-SOFM Toolbox by Alexandros Leontitsis
A toolbox to implement Spherical Self-Organizing Feature Maps

Contents.m
% S-SOFM Toolbox
% Version 1.0(beta) 23-Mar-2006
%
% Tested under Matlab 7.0.0.19920 (R14)
%
% This toolbox contains a set of functions and a GUI which can be used to
% create glyphs from spherical Self-Organizing Feature Maps (SOFMs). It is
% freely distributable for educational and research purposes.
%
%
% Example:
%
% load henon-1024-4.mat                   % loads the data to be visualized
% load c4-24.mat                          %loads the S-SOFM structure
% [w,g,r]=trainGlyph(P,X,C,0.5,20,'plot');%trains the S-SOFM
% glyph(X,r);                             % plots the S-SOFM
%
