yes, here

load fisheriris;
eva = evalclusters(meas,'kmeans','CalinskiHarabasz','KList',[1:6])

this is the usual silouhette plot used for k-means clustering:

load('kmeansdata.mat')
[idx3,C,sumdist3] = kmeans(X,3,'Distance','cityblock','Display','final');
[silh3,h] = silhouette(X,idx3,'cityblock');
xlabel('Silhouette Value')
ylabel('Cluster')
