That's an example from the Conbinatorica manual, which is included in the electronic help texts of Mathematica. No need to search the internet for that. MakeGraph and Subsets can be found there as well. Apparently you haven't thought of reading the manual before asking questions... Could you provide an example of the matrix or graph you tried?
