V=I*R. 1A current is applied to node a to b. Therefore, Va=Rab. Nodal voltage method is used.

Gii is the number of resistances connect to node i. Gii=3 means node i has 3 resistances. Gij is -1 when between node i to j has resistance

1/1 ohm = 1 S, so conductance = number of resistance

That's correct, 2R!
