Details:

The function "inconsistent" computes the inconsistency coefficient for each
link of a hierarchical cluster tree, which is usually the output of the
"linkage" function.

This is an example from the MATLAB documentation (where I substituted
"gallery('uniformdata',[10 2], 12)" with its values for reproducibility):

>> X = [.5266 .3142; .7502 .4603; .6655 .6940; .9640 .0014; .1082 .5530; .9314
.8254; .6781 .3419; .9827 .7046; .6147 .0470; .5802 .9174];
>> Y = pdist(X);
>> Z = linkage(Y, 'single');
>> inconsistent(Z)
