Re: [julia-users] How to make vector 'c' such that they are the values of the vector "a" but not in the vector "b"?

Thx, 
my idea was to long;)

c=copy(a)
deleteat!(c,findin(a,b))

Re: [julia-users] How to make vector 'c' such that they are the values of the vector "a" but not in the vector "b"?

[Tamas Papp]

Perhaps

setdiff(a, b)

or

a[indexin(a, b) .== 0]

I don't know which is faster, for small arrays it should not matter.

Best,

[julia-users] How to make vector 'c' such that they are the values of the vector "a" but not in the vector "b"?

How to make vector 'c' such that they are the values of the vector "a" but not 
in the vector "b"? 

(Excluding the value of b with a )

julia> b=[1 2 5]
1x3 Array{Int64,2}:
 1  2  5

julia> a=[1:1:10]
10-element Array{Int64,1}:
  1
  2
  3
  4
  5
  6
  7
  8
  9
 10

expected c: 3 4 6 7 8 9 10
