How to find the corresponding vector?

x = [1 2 3 4 5];

d = [0 10 20 30 40
10 0 50 60 70
20 50 0 80 90
30 60 80 0 100
40 70 90 100 0];

Dist = zeros(1,n);
for k=1:n
xp = randperm(numel(x), 2);
x(xp) = x(fliplr(xp))  % vector x permuted in two positions
s = sub2ind(size(d),x(1:end-1),x(2:end ));
Dist(k) = sum(d(s));
Distance = Dist(1,k)  % travaled distance by elements of the vector x
end
Lowest_Distance = min(Dist)

I need to find the vector x corresponding to Lowest_Distance.

For exemple:

>>

Lowest_Distance = 170

x=

1 2 3 5 4

Dist = zeros(1,n);
Distx = zeros(n,numel(x));  % <-- ADDED, allocate for saved x vectors
for k=1:n
xp = randperm(numel(x), 2);
x(xp) = x(fliplr(xp))  % vector x permuted in two positions
s = sub2ind(size(d),x(1:end-1),x(2:end ));
Dist(k) = sum(d(s));
Distx(k,:) = x;  % <-- ADDED, save the x vector for this iteration
Distance = Dist(1,k)  % travaled distance by elements of the vector x
end
[Lowest_Distance,ix] = min(Dist); % <-- MODIFIED, get the index of the min
Lowest_Distancex = Distx(ix,:); % <-- ADDED, pick off x vector corresponding to the min
