having trouble with for loops

Having Trouble...

'Sum of N^2 with N = 1 to 1,000 using a for loop'

Answer 1

[Andrei Bobrov]

out = 1;
for ii = 2:1000
   out = out + ii^2;
end

[Joseph]

    SumN=0;  % initializes N^2
    for N=1:1000
       SumN = SumN + N^2;
    end
        Still not giving me correct answer...Don't know what I'm doing wrong

[Thomas]

what answer do u expect?

[Joseph]

i got it thanks

Answer 2

[Roger Stafford]

Here's a way to check your answer:

 n = 1000;
 s = n*(n+1)*(2*n+1)/6;

This gives you the same value as

 s = sum((1:n).^2);

Answer 3

[Alonso Mukendi Kalonji]

a = 1;

n= 1000;

for i = 1: n

a = a+i^2

end

disp(a)
