I want to include a vertical line on the histogram, so it shows the location of the mean. The mean value is 5.12, how can I modify this code?

subplot(2,1,1)
histogram(LotH);
grid on;
title("Graph of (LotH)");
xlabel("LotH");
ylabel("Scores");
hold on;
line([0,5.12], ylim, 'LineWidth', 2, 'Color', 'r');

You are not plotting a vertical line. The coordinates you're using are (0,y_min) and (5.13,y_max), which is not a vertical line. You need to use this:
line(5.12*[1 1],ylim)
Or consider using the xline function (introduced in R2018b)
