Imagine, we have the following two array of numbers
A=[ 2 4 6 7 8 8];
B=[ 5 8 2 5 0 5];
Problem:
---------
we want to sort A and then arrange B according to the index of A.
Solution:
----------
>> [sortedA,indexA]=sort(A)
sortedA =
2 4 6 7 8 8
indexA =
1 2 3 4 5 6
>> B(indexA)
ans =
5 8 2 5 0 5
A=[ 2 4 6 7 8 8];
B=[ 5 8 2 5 0 5];
