Function of struct_property().

% Work out value for individuals, adjacency matrix, distance matrix, give back the structure struc_data

% clust_point: cluster individuals of per line

% num_categ: numbers of cluster

% A: initial data adjacency matrix

% D: initial data distance matrix

% struc_data

 data(i).point = ; % individual of the cluster
