- scipy.cluster.hierarchy.is_monotonic(Z)[source]¶
Returns True if the linkage passed is monotonic.
The linkage is monotonic if for every cluster
and 
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.
