Hi
I'm trying to calculate the eigenvector correspondent to largest eigenvalue of
graph.
The result obtained by"eigen" and "evcent" function were completely different
although their eigenvalue were equal.
I wanna know how it it is explained and which one is more reliable?
In the following, you can see an example
Best Regards
B.S
sw<-watts.strogatz.game(1,20,2,0.01)
m<-eigen(get.adjacency(sw))
e=evcent(sw)
m$value[1]
[1] 4
e$value
[1] 4
m$vector[1,]
