scipy.cluster.hierarchy.correspond

scipy.cluster.hierarchy.correspond(Z, Y)

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.
