您可以修改元素的css类。 CSS选择器为n：（var(Sn(40,:))用于选择名为NAME的类，% with n = 10000 var(Sn(40,:)) % var(S_40) = 30 (will vary slightly depending on random seed) (40/12)*((UB-LB)^2) % 29.9505用于选择具有标记名a的子元素。）

step = 0.01;
Domain = 40:step:80;

mu = 40*(LB+UB)/2;
sigma = sqrt((40/12)*((UB-LB)^2));

figure, hold on
histogram(Sn(40,:),'Normalization','pdf')
plot(Domain,normpdf(Domain,mu,sigma),'r-','LineWidth',1.4)
ylabel('pdf')
xlabel('S_n')
