I am new to MatLab. I have an array of data such as
sample1=[0.7,1.2,1.5,2.0,1.3,1.7,2.2,2.5,3.6, ....];
I want to plot the CDF and PDF of the data. Is there a easy way to do this?
Thanks!

[p,x] = hist(sample1); plot(x,p/sum(p)); %PDF
[f,x] = ecdf(sample1); plot(x,f); %CDF
Ckeckout help hist to see how to control the points at which you want to compute the probability densities.
