I am trying to define an array with:
- one dimension filled by another one dimensional array Int64
- the other dimension filled by regular numbers Int64
How can I do this? The dimensions are x and y.

Your question seems contradictory, and appears to be asking for something that is not logically possible, or that makes no sense. Are you perhaps using the word 'dimension' wrong? And what do you mean by 'array' (vector, matrix or higher-dimensional)?

I think you are mixing up arrays and the indices of the arrays. What you wrote now just means "element numberiinarr1is set equal to element(l, arr3[k])ofarr2". It doesn't explain what is actually insidearr2, just that it is a 2-dimensional array, and thatarr1andarr3are vectors.

arr3is a vector, but we don't know whatarr3[k]is, except that it is an element inarr3. I assume it is an integer number, since you are using it as an index.

Your use of "dimension" is vague, but perhaps you want a Matrix{Number}:
julia> array = Matrix{Number}([1.5 2.5; 1 2])
2×2 Array{Number,2}:
1.5 2.5
1.0 2.0

your question is not clear. Another possible answer is that you need a Vector of Vectors (rather than a Matrix)
julia> arr = Vector{Int64}
0-element Array{Array{Int64,1},1}
julia> push!(arr,[1,2,3])
1-element Array{Array{Int64,1},1}:
[1, 2, 3]
julia> push!(arr,[4,5,6])
2-element Array{Array{Int64,1},1}:
[1, 2, 3]
[4, 5, 6]
