[~,idx] = ismember(b,an)
b_swapped = bn(idx)

only direct swap only. 2 to 4 and 4 to 0 directly.. no swap 2 to 0

My algorithm does direct swap only. Run this code:
an = [2 3 5 6 0 1 4];
bn = [4 5 1 3 2 6 0];
b = [4 3 2 5; ...
1 0 6 2; ...
3 2 5 1];
[~,idx] = ismember(b,an);
b_swapped = bn(idx)
I get
b_swapped =
0 5 4 1
6 2 3 4
5 4 1 6
Isn't this exactly what you want?
