I have vector 1x5 (1,5,3,2,8) and I like to do cumulative sum of that. So the answer should seems like (6,9,11,19). Can you help me how to do it without loop?

x = [1,5,3,2,8];
cumsum(x)
but the first element is 1, not 6 as you have indicated. Of course, if you don't want that first element, you can do:
x = [1,5,3,2,8];
y = cumsum(x);
y = y(2:end);
