using index to assign an element

hello, I have this:

hjj = [0.6 0.4 0.9 0.7;0.8 0.7 0.9 0.5;0.8 0.6 0.5 0.4;0.8 0.5 0.6 0.5];
[weighh,idx] = sort(-sum(hjj,2));    
hjx = hjj(idx,:)
[Maxx_1,idd] = max(hjx,[],2);
[Minn_1,ide] = min(hjx,[],2);
tempp = ide(1);
ide(1) = idd(2);
idd(2) = tempp...

I want to swap the position of idd(2) with ide(1), such that the new matrix becomes

[0.8 0.7 0.9 0.9;0.6 0.4 0.5 0.7;0.8 0.5 0.6 0.5;0.8 0.6 0.5 0.4]

Thanks

Today I have selected the code with the mouse and hit the "{} Code" button to make the code readable. Please do this by your own in the future. Thanks.

The question is not clear, even after your comment below. Why does

          0.6          0.4          0.9          0.7
          0.8          0.7          0.9          0.5
          0.8          0.6          0.5          0.4
          0.8          0.5          0.6          0.5

get

          0.8          0.7          0.9          0.9
          0.6          0.4          0.5          0.7
          0.8          0.5          0.6          0.5
          0.8          0.6          0.5          0.4

? The given explanation matches the first 2 columns, but why does the 3rd column contains a 0.5 instead of a 0.9 after the conversion? And where does the 0.9 come from in the 4th column?

Please take the time to explain the procedure more clearly.

Peter which goal do you want to achieve?

[Peterikye]

My goal is to change the location of the minimum element in the upper row with the maximum element in the next lower row, until i have a situation where the minimum element in the upper row is greater than or equal to the maximum element in the next lower row. Thanks

Can't you simply just use a for loop and the min() and max() functions? It's trivial.

Use sort.
