[julia-users] Re: hcat with empty []

[Ethan Anderes]

Thanks Ivar. That looks way better. I hadn't thought to use hcat on 
Array{Vector, 1} since I didn't really understand the ellipsis operator within 
a function call: hcat(a_tmp) vrs hcat(a_tmp...). Playing around I guess 
hcat(a_tmp...) is just hcat(a_tmp[1], a_tmp[2], ...). Cheers!
