MATLAB: Duplicated result in for loop

Question

powerr = [ ...
 0.6164    3.4161    0.9950    3.4117
 3.1654    0.4123    4.2391    1.0198
  0.5745    3.0364    1.3191    3.1129
  2.9883    0.7348    3.8730    0.4123
  0.9381    3.3749    2.0421    3.5014
  2.1817    1.0630    3.0643    0.9487];
k = 3;
m = k;
croppedz = powerr(1:end-mod(end, 2*m), :);
result = zeros(size(croppedz, 1) / 2 / m, size(croppedz, 2));
for lol = 1 : size(croppedz, 2)
  hh = powerr(1:3);
  gg = powerr(4:6);
  n = m*fix(numel(hh)/m);
  result (:, lol) = sum(reshape(sort(hh(1:n), col),m,[]),1) ./ ...
                    sum(reshape(sort(gg(1:n), col),m,[]),1); 
end
disp(result)

I am getting the result

0.7132    0.7132  0.7132  0.7132

instead

0.7132   1.3271  0.7298  1.5515

thanks in advance

Answer 1

The body of the loop does not depend on the loop counter lol. Therefore you must get the same value for each iteration.

A bold guess of what you want instead:

for lol = 1 : size(croppedz, 2)
  hh = powerr(1:3, lol);
  gg = powerr(4:6, lol);
