# I dont understand this

I don't understand why the array size of A, labels and xy are not the same. As far as I know, A is a matrix which contain number of how many times a node links to the other. Labels should be the list of all nodes. And xy is representing the co-ordinate of all nodes. However as shown in the cs-standford.mat, matrix A is 9914X9914, labels is 9914X1, and xy is 21X2 ! why?
