Graph proximity model

To get the Katz measure of co-occurence matrix AA' call function Katz(A,A1,c), where c is the number of desired group recommendations. To get the Katz measure of combined adjacency matrix C call function KatzC(A,A1,S,lambda,c), where c is the number of desired group recommendations, and lambda is a parametar that controls ratio of the weight of friendship to the weight of group membership (usualy used is lambda=0.2).

Tex
