# 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.
