I have earlier used a similar expression to calculate the sum using a for loop (without limits) and it looked like this:
for N=1:100
S(N)=S(N-1)+(1/N^2)
end
In this case I need to create a while loop how do I start?
/ I am a super-beginner at matlab

"How do I write a script that calculates and prints all values for N according to the following expressions and limits?"
k = 0;
s = 0;
while s<=1.62
if s>=1.6
disp(k)
end
k = k+1;
s = s+1/k^2;
end

N=1;
% sum function uses an internal loop
% find the first N that sum is >= 1.6
while sum(1./[1:N].^2) < 1.6
N = N+1;
end
disp(N)
% find the end N
while sum(1./[1:N].^2) <= 1.62
N = N+1;
end
disp(N-1)
% the answer is 22 through 39
