n=input('Enter the number that should not exceed:');
fibonacci(1)=input('Enter the first number:');
fibonacci(2)=input('Enter the second number:');
f(1) = 1;
f(2) = 1; 
for i = 3 : 30
    % SUM
    f(i) = f(i-1) + f(i-2);
    golden_ratio = f(i)/f(i-1);
    str = [num2str(f(i)) ' ' num2str(f(i-1)) ' ' ...
    num2str(golden_ratio, 10)];
    disp(str)
end

What is the error? What is not as expected?

What about this:

lim  = 10000;
f(1) = 1;
f(2) = 1;
for i = 3 : 30
  f(i)         = f(i-1) + f(i-2);
  golden_ratio = f(i) / f(i-1);
  fprintf('%d: %d %d %.16g\n', i, f(i), f(i-1), golden_ratio);
  if f(i) > lim
    break;  % Stop the "for i" loop
  end
end
