I’m scratching my head around a small problem but I can’t find a vectorized solution. I have 2 arrays A and B and I would like to get the indices (relative to B) of elements of A that are in B:
>>> A = np.array([2,0,1,4]) >>> B = np.array([1,2,0]) >>> print (some_function(A,B)) [1,2,0] # A[0] == 2 is in B and 2 == B[1] -> 1 # A[1] == 0 is in B and 0 == B[2] -> 2 # A[2] == 1 is in B and 1 == B[0] -> 0 Any idea ? I tried numpy.in1d with no luck.
