G = gsp_swiss_roll(N,rand_state,param);
| N | Number of vertices. |
| s | sigma ( default: sqrt(2/N)) |
| thresh | threshold (default: 1e-6) |
| rand_state | rand seed (default: 0) |
| G | Graph structure. |
'gsp_create_swiss_roll(N,s,thresh,rand_state)' initializes a graph structure containing the swiss roll graph
Example:
G = gsp_swiss_roll(200); gsp_plot_graph(G);
