scipy.cluster.hierarchy.correspond(Z, Y)[source]

Checks for correspondence between linkage and condensed distance matrices

They must have the same number of original observations for the check to succeed.

This function is useful as a sanity check in algorithms that make extensive use of linkage and distance matrices that must correspond to the same set of original observations.

Parameters :

Z : array_like

The linkage matrix to check for correspondence.

Y : array_like

The condensed distance matrix to check for correspondence.

Returns :

b : bool

A boolean indicating whether the linkage matrix and distance matrix could possibly correspond to one another.
