				function [mom2, loglik] = normalize_pot(can)				% NORMALIZE_POT Convert the canonical potential Pr(X,E) into moment potential Pr(X|E) and return log Pr(E).				% [mom, loglik] = normalize_pot(can)								mom = cpot_to_mpot(can);				mom = struct(mom); % violate privacy of object				loglik = mom.logp;				%mom.logp = 0; % now represents Pr(X | E) instead of Pr(X, E). 				mom2 = mpot(mom.domain, mom.sizes, 0, mom.mu, mom.Sigma);
