scipy.cluster.hierarchy.correspond

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

Checks if a linkage matrix Z and condensed distance matrix Y could possibly correspond to one another.

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.

Arguments :
  • Z : ndarray

    The linkage matrix to check for correspondance.

  • Y : ndarray

    The condensed distance matrix to check for correspondance.

Returns :
  • b : bool

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