Let Wcell be a cell with the adjacency matrices of each layer , p the power of the power mean Laplacian, y an array with the class of labeled nodes (zero denotes node is unlabeled). Classes through the power mean Laplacian L_p regularizer are computed via

y_hat = SSL_multilayer_graphs_with_power_mean_laplacian(Wcell, p, y);
