Let’s say, the first column represents the trip number in a train station. The other columns represent the number of passengers coming from different gates (g1 g2 g3...g10). So if the trip number is not repeated (which means there is only one trip a day), then put all passengers in one train. If the number is repeated (two shifts or more, in the morning, other in the evening & last at night).Take the passengers from 3 gates which have the largest number of passengers in the morning, other 3 in the evening & last group at night.

end
Trip #  g1  g2  g3  g4  g5  g6  g7  g8  g9  g10  
82  10  16  15  66  76  71  83  44  49  
91  28  98  43  4  75  4  70  39  45  
13  55  96  92  85  40  28  32  77  65  
92  96  49  80  94  66  5  96  80  71  
64  97  81  96  68  18  10  4  19  76

The result should look like this:


   82     76     71      66    49    44        16    15    10
    1      6      7       5     10     9        3     4      2
4, 1:
  91    75    70    45
   1    6     8     10
4, 2:
  39    28     4     4
   9     2      5     7
1, 4:
  96    94    92    80
    8    5     1      4
1, 5:
  71    66    49     5
   10     6    3      7

I want to know what is wrong with this solution
finalresult=[];
for i=1:4
    if true
      % code
    end
  for j=i+1:5
  result1=[];
  result2=[];
    result3=[];
    if w(j)~=w(i)
    [a,b]=sort(r(i,:),'descend');
    presult1=b;
    else
    [c,d]=sort(r(j,:),'descend');
    presult2=d(1:3);
    presult3=d(4:6);
    end
    result1=[result1;presult1];
    result2=[result2;presult2];
    result3=[result3;presult3];
    end
    end
        if true
          % code
        end
