scipy.cluster.hierarchy.is_monotonic(Z)[source]

Returns True if the linkage passed is monotonic.

The linkage is monotonic if for every cluster s and t joined, the distance between them is no less than the distance between any previously joined clusters.

Parameters :

Z : ndarray

The linkage matrix to check for monotonicity.

Returns :

b : bool

A boolean indicating whether the linkage is monotonic.
