Error when evaluating clusters of a dataset

I'm trying to evaluate the number of a dataset, data is described bellow and clust are the results of a clustering algorithm (vector of classes):

eva=evalclusters(data,clust,'CalinskiHarabasz');

Depending on the data input I'm receiving almost all time the error:

Error using clustering.evaluation.ClusterCriterion (line 447)
The number of clusters to be evaluated must be different for different clustering solutions.

How can I solve the error? Columns are properties and rows are observations in the data array. Error seems to be in the clust array:

It looks like your next-to-last column, which has cluster numbers up to 9, is missing cluster 6 so it only has 8 clusters. I believe the evalclusters function wants to help choose the number of clusters, and it's not prepared to deal with two different clustering solutions both with 8 clusters.

It worked!, Thank you

Hey!

I am facing the same error. Here, the number of clusters are 5 and I see that all clusters have some data points assigned as seen in the histogram plot. Can you help me understand how to resolve this ?

Thanks!
