MATLAB: Incidence matrix of a graph

Question

Hello,

Is there any way to create a incidence matrix of a graph. For example, for IEEE 7-bus system I have branch data like this:

1 2

2 3

2 7

2 6

3 6

3 4

4 7

4 5

And I need incidence matrix to be like this:

Or, maybe better solution, to give me numbers of nodes which are mutualy connected, for example

1 2 (node 1 is connected to node 2)

1 2 3 6 7 (node 2 is connected to nodes 1, 3, 6, 7)

2 3 4 6 (node 3 is connected to nodes 2, 4 and 6)

etc.

Thanks!!!

If you have constructed a graph() object named G, then

full(G.adjacency)
