Sorting a vector by another vector with same terms

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?

Answer 1

[Stephen23]

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
