Hi Chris,
Unfortunately I don't know why the type changes from Array{Array{Int64,1},1}
to Array{Any,1}. But I have a suggestion to what you can do to keep it as
Array{Array{Int64,1},1}.
My initial shot would be to do a + [[1,1] for i = 1:5] instead of a + 1:
julia> a + [[1,1] for i = 1:5]
5-element Array{Array{Int64,1},1}:
[2,2]
[2,2]
[2,2]
[2,2]
[2,2]
Or, if you want to simplify the way you do it, just define a function like
this:
julia> function newsum(a::Array{Array{Int64,1},1}, i::Int)
lengtha = size(a,1);
return([[i,i] for i = 1:lengtha])
end
newsum (generic function with 1 method)
julia> newsum(a,1)
5-element Array{Array{Int64,1},1}:
[1,1]
[2,2]
[3,3]
[4,4]
[5,5]
But I am sure you will find many more suggestions here! ;)
Best,
Charles
