cluster
Construct agglomerative clusters from linkages
Syntax
Description
defines clusters from an agglomerative hierarchical cluster tree T
= cluster(Z
,'Cutoff'
,C
)Z
.
The input Z
is the output of the linkage
function for an input data matrix X
.
cluster
cuts Z
into clusters, using
C
as a threshold for the inconsistency coefficients (or inconsistent
values) of nodes in the tree. The output T
contains cluster assignments of each observation (row of X
).

Alternative Functionality
If you have an input data matrix X
, you can use clusterdata
to perform agglomerative clustering and return cluster indices for
each observation (row) in X
. The clusterdata
function
performs all the necessary steps for you, so you do not need to execute the pdist
, linkage
, and cluster
functions separately.
