I have two 2x4 matrices A and B. I have rearranged A in decending order and have obtained the index for this rearrangement. I would like to use this index to rearrange B. However, when I try that, it is is only working for the 1st column and using the values from this column for the rest. How do I rectify this?
Here is my code:
A = rand(2,4);
B = rand(2,4);
[C,idx] = sort(A,'descend');
D=B(idx);

A = rand(2,4);
B = rand(2,4);
[C,idx] = sort(A,'descend');
D=B;
for i = 1:size(idx,2)
D(:,i) = B(idx(:,i),i) ;
end
