Hi,

I could not find a direct function in MATLAB for hierarchical k-means clustering. However, You can first use the k-means clustering algorithm to get the centroids of the clusters. For this you can use the " kmeans " function.

Once you have your clusters from k-means, then you can use the hierarchical clustering for further grouping the data into clusters.
