I get this error when using gdlCluster

Error using gacPartial_sort
Rank is out of the range.

Error in gacMink (line 11)
        [sortedDist, NNIndex] = gacPartial_sort(X, k, dim);

Error in gacBuildDigraph_c (line 24)
[sortedDist,NNIndex] = gacMink(distance_matrix,max(K+1,4),2);

Error in gdlCluster (line 38)
    [graphW, NNIndex] = gacBuildDigraph_c(distance_matrix, K, a);
