normalization of a matrix

I am trying to implement this paper. In the paper the equation 2 says P_i = 1/K * (1/1-M_i) where where K is a normalization factor to make max_i P_i = 1. can anyone suggest a way to compute P_i in matlab. I have calculated the matrix M using a equation described in the paper.

How about this?

m = rand(3) ;
p_i = 1./(ones(3)-m) ;
p_i = p_i/max(p_i(:)) ;
