Kohonen networks are also called Self Organizing Maps and https://www.mathworks.com/help/nnet/ug/self-organizing-feature-maps.html will provide some information about how you can use SOM with MATLAB. http://www.sis.pitt.edu/~ssyn/som/som.html has some good notes as well. http://www.cis.hut.fi/somtoolbox/ is the toolbox designed for SOMs that you may find useful.
