Subject: Using Intersect Without Removing Repetitions

I would like to do the following:

[C ind] = intersect(A,B);

Where A(100,1), is a vector with a list of consecutive values from 1 to 1000 in a random order (i.e. value 3 is in row 11),
And B (5,1) is a vector with a shorter list of values all of which occur in A at some location. However there are some repetitions i.e. [1 3 5 5 70] ...

I would like my output vector 'ind' to account for these repetitions in B, such that the index in A repeats itself. i.e. for the above example ind = [ 1 11 25 25 100].

Any help regarding this would be much appreciated,

Thanks!
