OK, let it be so. The implementation of graph connectives using the 
adjacency matrices isn't too difficult. Regarding adjacency lists or 
incidency matrices, it's more difficult and intererestring to perform 
such operations.
I meant that it's more convenient to do the operations for adjacency 
matrices and then to convert them into another graph representation, but 
now I doubt that this will be more effective (it needs some time to 
convert a graph from one representation to another (and a lot of 
memory), and the algorithm needs time and memory, too).
