i want to know how to use nmi.m toolbox to test the new partition.

for example: this graph with 7 nodes, and 20 edges "the graph that represent it without any partition " and the original partition is , where node {1,2,3,4} is at the same cluster and nodes{5,6,7}is in another cluster. the new partition has the same clustering ,so NMI=1 for this example . i want to use this toolbox "nmi.m" to calculate the normalized mutual information for a large graph
