Hi, Thank you very much. I tried in that way. However the probability exceeds 1.0 in histogram. I can't find how to fit it.
clear all; close all; DA = xlsread('exceltomatlab.xls','Sheet1', 'B2:B2290'); muDA = mean(DA); stdDA = std(DA); binStep=0.1; binCenters = 0.05:binStep:0.95; % Compute the histogram scaling factor. (If all histogram counts are in a % single bin, the probability = 1) binCount = histc(DA,binCenters); probScale = sum(binCount)*binStep; % Plot the normalized histogram and change the bar color for line % visibility histHandle = bar(binCenters,binCount/probScale,'hist'); set(histHandle,'FaceColor',[0.5,0.5,0.5]); hold on; % Overlay the distribution fit on the histogram x = binCenters; y = normpdf(x,muDA,stdDA); plot(x,y); xlabel('Data'); ylabel('Probability');
I hv attached the excel file as well.

Please add your comment to the original post. Don't forget to attach your file there as well. No one should respond to this one.

What is this in reply to?
Why is your code so unreadable?
