assign order to different vector
显示 更早的评论
hey
i want to determine the order of every element in a vector and apply this order to another vector. say i have a vector [0, 1, -1, 3, 5] so when ordering this vector according to its size one would have 2,3,1,4,5. So now i want to transfer this order to a second vector which is ordered by size in the following way: [10, 11, 12, 13, 14]. Applying the order of the first vector this would yield: [11, 12, 10, 13, 14]. How can this performed in matlab?
thanks for your help!

How do you figure that 2,3,1,4,5 is the order for [0, 1, -1, 3, 5] ?

[junk, idx] = sort(A);
reordered_B = B(idx);
