kruskalwallis performs a nonparametric one-way analysis of variance by ranks. When X is a matrix and group is empty, columns are treated as groups. When X is a vector, group supplies one group label per observation.
displayopt can be 'on' or 'off'. NaN observations are omitted.
X = [6 7 8; 5 7 9; 4 8 NaN; 6 9 10];
