Copy
public static (IReadOnlyList<AltaxoVariant> ClusterValues, IReadOnlyList<double> ClusterStdDev, IReadOnlyList<int>? ClusterIndices) ClusterValuesByKMeans(
	DoubleColumn col,
	int numberOfClusters,
	SortDirection sortDirection,
	bool createStdDev
)

Parameters

col  DoubleColumn
The column containing the data to be clustered.
numberOfClusters  Int32
The number of clusters to create.
sortDirection  SortDirection
The sort direction of the cluster's centroids.
createStdDev  Boolean
If set to true, the standard deviation of each cluster will be calculated.

Return Value

ValueTupleIReadOnlyListAltaxoVariant, IReadOnlyListDouble, IReadOnlyListInt32
