For/if loop for adding up only odd numbers
显示 更早的评论
Hi,
We're supposed to write a loop (it must be a loop!) to calculate the following expression (see attached image). We're supposed to only sum the values that correspond to odd values of n.
This is what I got so far but I don't know how to specifiy that only only odd values for n are added.
for n = 1:100
c(n) = (1/(n^2));
sum(c);
end
Can anybody help me with that please?
Thanks,
Debbie

You mean this?
for n = 1:100
if mod(n,2) == 1
c = (1/(n^2));
sum(c);
end
end

Little bit different for negative value. Same for positive:
