Hi everyone,
I have something like 2000 samples (data recorded during 3 months) of wind speed from anemometer all saved in excel. How can I plot the distribution in MATLAB?

Hi, I know this is very late response. I just saw your question.. Sorry ;)
If you didn't solve your problem yet.. Here is the solution.. You can plot the distribution,
%%histogram and weibul
a= 8.1; % Scale factor
b= 3.4; % Shape factor
q1 = size(U); % No of wind measurements
[h1 x1] = hist(U,20); % histogram with 20 bins for clear visual effect
bar(x1,h1) % Make a histogram plot
hold on
w1=wblpdf(U,a,b); % Weibull
plot(U,w1*q1,'r')

One way to obtain c is the following:
c = 1.12u
where u is the mean velocity of your data
k = (〖s/u)〗^(-1.086)…. in which s is the standard deviation
