nodes' numbers can also be represented as a range k=1:M, where M is known
How to plot node numbers using matrix of nodes's coordinates?

Hi, my script plots a mesh grid using:
where 'adj' is the adjacency matrix and 'NC' is the matrix of nodes' coordinates. It works absolutely fine, except for the fact that it doesn't plot the nodes' numbers on the graph.
For example, for a grid like this:
| | |
| | |
I need nodes' numbers to be on the graph and the nodes coordinates matrix is given by:
Where h's and w's are user's inputs.
The script also provides the matrix of nodes numbers, which for this example looks like this:
1 4 7
2 5 8
3 6 9
I believe it is possible to use the above matrices to plot the nodes' numbers, but I don't know how. Any ideas?

And text() doesn't give you the results you'd like? E.g.
k = 1:30;
[B,XY] = bucky;
If that's not good enough, we could certainly do some cosmetics on it...

Can We set locations of Nodes by coordination method? For example, Node1 is at x=3, y=4 of each axis. Please see following figure!In figure, all Nodes are located at wherever they want. We want to locate those Nodes systematically. Please answer is it possible or not!
