How can I list the set of partitions (clusters) in hierarchical clustering at each level?

For example, consider

D_tr=rand(10,1);

D=0.5*(D_tr+D_tr');

tree = linkage(D,'average');

dendrogram(tree)

All the instructions to find out how the hierarchical structure is built is described in the help page Linkage, Output Arguments Z. Did you figure it out?

Unfortunately No. It is not clear because Z includes new indices etc (and you have to figure out these new indices to get the original data flow during clustering process) . I was expecting that there should be some direct way to obtain the resulting clusters and their data content. The developers of the code should update the commands to include the features I mentioned and otherwise it is a pain.
