聚类树的matlab软件包。层次聚类分析器。(ClusTree is a GUI Matlab tool that: Enables an easy and intuitive way to cluster, analyze and compare some hierarchical clustering methods Consists of a two-step wizard that wraps some basic Matlab clustering methods and introduces the Top-Down Quantum Clustering algorithm. Provides a flexible and customizable interface for clustering data with high dimensionality. Allows both textual and graphical display for the clustering results. Can either apply hierarchical clustering to a dataset or analyze ‘pre-clustered’ results. )
