Below is a brief outline of this course. The tree is not a single set of clusters, but rather a multilevel hierarchy, where clusters at one level combine to form clusters at the next level. The theory behind these methods of analysis are covered in detail, and this is followed by some practical demonstration of the methods for applications using R and MATLAB. At each step, the two clusters that are most similar are joined into a single new cluster. The following Matlab project contains the source code and Matlab examples used for trims the sahn tree, z, generated by the function, linkage to correspond to cluster(z,'maxclust',m).
