贝叶斯网络的matlab实现。可以创建贝叶斯网络、训练模型

				function [m, pot] = marginal_nodes(engine, query)
				% MARGINAL_NODES Compute the marginal on the specified set of nodes (global_joint)
				% [m, pot] = marginal_nodes(engine, query)
				
				pot = marginalize_pot(engine.jpot, query);
				m = pot_to_marginal(pot);
				%[m.T, lik] = normalize(m.T);
				%loglik = log(lik);
