Sum of first 100 integers?

Write a script that uses a for loop to calculate the sum of the first 100 integer numbers

Answer 1

[Mischa Kim]

my_sum = 0;
for ii = 1:100
  my_sum = my_sum + ii;
end

[Lukeus Perez]

You're the best

Answer 2

[Sean de Wolski]

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

Answer 3

[Roger Stafford]

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!

[Jan]

This means as code:

n = 100;
s = (n * (n + 1)) / 2

Answer 4

[Mayur Gaikwad]

Could someone write the script for matlab mobile version for the sum of the squares of first 100 natural numbers.. !

[Jan]

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.
