Let's say we have a vector A = [1,4,2] and we wish to sort it according to the order given by B = [4,5,1,2] The end result should give A = [4,1,2]. Is there an existing way in Matlab to accomplish this?

Method 1 using intersect:
>> intersect(B,A,'stable')
ans =
4 1 2
Method 2 using intersect's returned indices:
>> [~,~,X] = intersect(B,A,'stable');
>> A(X)
ans =
4 1 2
Method 3 using ismember:
>> B(ismember(B,A))
ans =
4 1 2
