yenidendonguyegirecekler = [
  -1321.6
  -2119.8
  -2825.5
  -2937.5
  -3205.4
  -3340.9
  -3895.0
  -4080.2
  -4320.9];
fitnesshafiza = [
  -4080.2
  -2937.5
  -2825.5
  -5749.6
  -3205.4
  -2119.8
  -3340.9
  -4320.9
  -3895.0
  -1321.6];

To find where the elements of yenidendonguyegirecekler are located in fitnesshafiza:

[~,idx] = ismember(yenidendonguyegirecekler,fitnesshafiza)

idx = 9×1

10 6 3 2 5 7 9 1 8

You can use the ismember function to find out whether each element of one vector is present in the other, and also the location.

for example ismember(A,B) ?
