Multidimensional Array Comprehension in Julia

Question

I\'m mucking about with Julia and can\'t seem to get multidimensional array comprehensions to work. I\'m using a nightly build of 0.20-pre for OSX; this could conceivably be

Answer 1

Your intuition was to write [(x, y) for x in 1:5, y in 6:10], but what you need is to wrap the ranges in zip, like this:

[i for i in zip(1:5, 6:10)]

Which gives you something very close to what you need, namely:

5-element Array{(Int64,Int64),1}:
(1,6) 
(2,7) 
(3,8) 
(4,9) 
(5,10)

To get exactly what you're looking for, you'll need:

hcat([[i...] for i in zip(1:5, 6:10)]...)'

This gives you:

5x2 Array{Int64,2}:
1   6
2   7
3   8
4   9
5  10
