scipy.cluster.hierarchy.average

scipy.cluster.hierarchy.average(y)

Perform average/UPGMA linkage on a condensed distance matrix.

Parameters:

y : ndarray

The upper triangular of the distance matrix. The result of pdist is returned in this form.

Returns:

Z : ndarray

A linkage matrix containing the hierarchical clustering. See linkage for more information on its structure.
