[Franck Dernoncourt]

The Statistics Toolbox implements the gap statistic as a class in the package `clustering.evaluation` since R2013b: http://www.mathworks.com/help/stats/clustering.evaluation.gapevaluationclass.html

    load fisheriris;
    rng('default');  % For reproducibility
    eva = evalclusters(meas,'kmeans','gap','KList',[1:6])
    figure;
    plot(eva);
