[Retracted] Text Clustering and Economic Analysis of Free Trade Zone Governance Strategies Based on Random Matrix and Subject Analysis

Algorithm 1

Coalescing method.

	Input: the set of samples D, the number of clusters 1.
	Output: all the sample points in the sample are set as a separate class cluster.
	repeat
(1)	Calculate the distance between the two class clusters and find the two smallest class clusters C1 and C2.
(2)	merge class clusters C1 and C2 into one cluster.
(3)	visualize the clustering results.
	until: coalesce into l classes.
