scipy.cluster.hierarchy.correspond¶
- 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.
