You *could* use setdiff, it depends on what you're working with (e.g. a
range of integers)
In [24]: a = [1:10]
Out [24]: 10-element Array{Int64,1}:
1
2
3
4
5
6
7
8
9
10
In [25]: b = [2,6,9]
Out [25]: 3-element Array{Int64,1}:
2
6
9
In [26]: setdiff(1:10,findin(a,b))
Out [26]: 7-element Array{Int64,1}:
1
3
4
5
7
8
10
