for ii = 100
s = sum(1:ii);
end

Or you could emulate the mathematical genius, Karl Friedrich Gauss, who is said to have done it this way at the age of ten:
s = (100+1)+(99+2)+(98+3)+...+(51+50) = 50*101 = 5050
(See: http://math.about.com/cs/mathematicians/a/gauss.htm)

Gotta love good ol' Gauss!

This means as code:
n = 100;
s = (n * (n + 1)) / 2

Yes. Simply add a "^2" in Mischa's answer.
Please do not inject a new question as an answer to an existing thread. Such thread-hijacking confuses the readers, because it is not clear anymore, to which question an answer belongs.
Because this sounds like a homework, let me encourage you to try to solve this by your own.
