How to display certain iterations
显示 更早的评论
%% Problem 3
clc;
n=1
k=1
sum=0
while n<15000
sum=sum+(2/(k^4))
n=n+1
k=n
end
I need to display the first 10 and the last 10 iterations, but I am not sure how to do it.
I was thinking using a ones or zeros function to store the values and then only display 1-10 and 14991-15000, but I cant remember how to execute that. Is that the way to go about this problem, if so how would I, or is there an easier way to solve it?

if (n >= some_lower_bound && n <= some_upper_bound) || (n >= some_other_lower_bound && n <= some_other_upper_bound)
disp(something appropriate)
end

%% Problem 3
clc;
n=1;
k=1;
sum=0;
dp = zeros(20,2);
i=1;
while n<15001
if(n<11 || n>14990)
dp(i,1)=n;
dp(i,2)=sum;
i=i+1;
disp(['n=', num2str(n),' sum=',num2str(sum)]);
end
sum=sum+(2/(k^4));
n=n+1;
k=n;
end
