How to arrange indices of a real array ?

if I have:

Rankig = [ 0.6229 , 0.6516 , 0.2036 , 0.0997 , 0.5986 , 0.5897 , 0.7667 , 0.4887]

I want to arrange indices from the big to the small, I tried

[B,Indexes] = sort(Rankig,'descend');

When I print [Ranking ; Indexes ], I found:

ans =

0.6229 0.6516 0.2036 0.0997 0.5986 0.5897 0.7667 0.4887

7.0000 2.0000 1.0000 5.0000 6.0000 8.0000 3.0000 4.0000

This method did not work, any help ?

I want the result be:

0.6229 0.6516 0.2036 0.0997 0.5986 0.5897 0.7667 0.4887

6.0000 7.0000 2.0000 1.0000 5.0000 4.0000 8.0000 3.0000

I mean 1 => the small value wich is 0.0997

2 => the second small value

etc ... and 8 => the big value 0.7667

You are just interpreting the output incorrectly.

[B, Indexes]

ans =

    0.7667    0.6516    0.6229    0.5986    0.5897    0.4887    0.2036    0.0997
    7.0000    2.0000    1.0000    5.0000    6.0000    8.0000    3.0000    4.0000    

B is the sorted values.

Interpret the output as "The largest value of Rankig has value 0.7667, and it is the 7th element."

Look the 4th and 5th

0.0997 > 0.5986 ????

It is an error

Here is the sorting, in descending order:

• 0.7667, which is the 7th element of Rankig
• 0.6516, which is the 2nd element of Rankig
• 0.6229, which is the 1st element of Rankig
• 0.5986, which is the 5th element of Rankig
• 0.5897, which is the 6th element of Rankig
• 0.4887, which is the 8th element of Rankig
• 0.2036, which is the 3rd element of Rankig
• 0.0997, which is the 4th element of Rankig

B is the values, from largest to smallest.

Indexes is the position in Rankig.

I'm not sure how else to explain it.

I understand you buddy and thank you for your anwser;

but I want to sort the results of the :

0.7667    0.6516    0.6229    0.5986    0.5897    0.4887    0.2036    0.0997

I mean I want the results be:

  7.0000    2.0000    1.0000    5.0000    6.0000    8.0000    3.0000    4.0000   

Do you understand me ?

Rankig = [ 0.6229  , 0.6516 ,  0.2036  , 0.0997 , 0.5986 , 0.5897 , 0.7667 , 0.4887];
[~,Indexes] = sort(Rankig); 
[~,Indexes2] = sort(Indexes);
output = [Rankig; Indexes2]

output =

    0.6229    0.6516    0.2036    0.0997    0.5986    0.5897    0.7667    0.4887
    6.0000    7.0000    2.0000    1.0000    5.0000    4.0000    8.0000    3.0000
