Just pass the dissimilarity matrix, number of clusters in the partition to be evaluated and the indexes for each data point and you will get the Dunn's index.The Dunn's index measures compactness (Maximum distance in between data points of clusters) and clusters separation (minimum distance between clusters). This measurement serves as a measure to find the right number of clusters in a data set, where the maximum value of the index represents the right partitioning given the index (partition with the highest separation between clusters and less spread data in between clusters).For more information about the Dunn's index check:Validity index for crisp and fuzzy clusters, Malay K.
