Dear all,
I cannot seem to get the cluster function to work. I know the data
plays a big role in the computation.. but visually i see 3 clusters in
the array. but it groups it into 1 cluster. ie there is nothing where
result=1

weights = CLUST_WTS(array, N_CLUSTERS = 3)
result = CLUSTER(array, weights, N_CLUSTERS = 3)
;Plot each cluster using a different symbol:
IPLOT, array[*, WHERE(result eq 0)], $
LINESTYLE = 6, SYM_INDEX = 2
IPLOT, array[*, WHERE(result eq 1)], /OVERPLOT, $
LINESTYLE = 6, SYM_INDEX = 4

please help
thanks
