Silly question Incorrect Calculation

I have a nested if statement that states if the condition is not met run another script and then compare again until it meets the condition or meets the maximum iterations.

unk_row = 6

for it_cnt = 1:20

      % for all elements in del_hat_cal (6 coords)
      for unk_cnt = 1:unk_row

      if (abs(del_hat_cal(unk_cnt,1))) < sqrt(C_x_hat(unk_cnt,unk_cnt)) 

          del_hat_cal = del_hat_cal

      % else if any of the values dont meet the requirements => run the iteration
      % subroutine.  
      else IterationSubscript_1_2

      end
   disp ('Iterations')
   disp(it_cnt)
      end

The code executes correctly until the second iteration of it_cnt

It then says that the if statement is met and del_hat_cal = del_hat_cal.

I.e. that

0.00102504692433755
0.000892842647618351
0.00348097622168141
0.00306579321936951
0.00315561723971564
0.000665510381349233

< sqrt [
1.20641569956672e-05
9.90305275269894e-06
3.62427182962373e-05
2.53803334328813e-05
4.60943640122694e-05
1.44380191794682e-05 ]

Does anyone know why in the second iteration for it_cnt MatLab shows the condition is met, thus del_hat_cal = del_hat_cal ?

but 0.00102504692433755 is less than sqrt(1.20641569956672e-05) which is approximately 0.003 . The condition is met.

My guess, based upon the comment in the code, is that you want

unk_row = 6

for it_cnt = 1:20

    % for all elements in del_hat_cal (6 coords)
    unk_cnt = 1:unk_row

    if all((abs(del_hat_cal(unk_cnt,1))) < sqrt(C_x_hat(unk_cnt,unk_cnt)))

      del_hat_cal = del_hat_cal

    % else if any of the values dont meet the requirements => run the iteration
    % subroutine.  
    else IterationSubscript_1_2

    end
    disp ('Iterations')
    disp(it_cnt)
  end
