Find the tail of array except first element
Is there a method to get the tail of a collection(e.g. vector) i.e. the array except the first element. Currently, I have
tail(arr) = selectdim(arr, 1, 2:length(arr))
julia> c
3-element Array{Int64,1}:
1
2
3
julia> tail(c)
2-element view(::Array{Int64,1}, 2:3) with eltype Int64:
2

Simply use the end
keyword:
julia> c = [11,12,13]
3-element Array{Int64,1}:
11
12
13
julia> c[2:end]
2-element Array{Int64,1}:
12
13

Also@view c[2:end]
