Check 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.
Z : array_like
The linkage matrix to check for correspondence.
Y : array_like
The condensed distance matrix to check for correspondence.
b : bool
A boolean indicating whether the linkage matrix and distance matrix could possibly correspond to one another.
