IHello Programmers,
I am trying to perform the following tasks.
1. I have a function that returns two vector as output and one of the vector must be arranged in ascending order for further computation.
2. The second vector would also need to be rearranged such that each element corresponds to the other vector origal element.
[A, B] = Executeprogram(C,D);
% The output of A & B are given below.
% The objective is to arrange A in ascending order such that each element
% of B will still correspond to A
A = 2, 5, -3, 10;
B = 3, 1, 4, 2;
% I want the final answer to be like
% A = -3,2,5,10
% B = 4, 3,1,2

A = [2, 5, -3, 10];
B = [3, 1, 4, 2];
[A,idx] = sort(A)
A = 1×4
-3 2 5 10
idx = 1×4
3 1 2 4
B = B(idx)
B = 1×4
4 3 1 2

Thank you so much.

[A,b]=sort(A);
B=B(b);
