Execute()

bool CSG_Cluster_Analysis::Execute	(	int	Method,
		int	nClusters,
		int	nMaxIterations = 0,
		int	Initialization = 0
	)

Performs the cluster analysis using the features added prior to this step. Method is minimum distance (= default), hill climbing (= 1), or both methods in combination. If nMaxIterations is set to zero, the analysis is iterated until it converges. Initilization is done randomely (= default), periodically (= 1), or skipped (= 2). The latter case allows starting the clustering with user supplied start partitions.
