Dear Community,  
I am trying to achieve the same result of [1 2 3], with a code spanning over multiple lines, i.e.  
[1  
2  
3]

However, the latter code returns a column vector.  
Since the population of the array is long, it is not possible for me to use the [1 2 3] approach in a single line, iwthout multipling significantly the number of lines to write.  
Is there an efficient way to do so?

Thank you,  
Davide

You can use

```julia
hcat(1,
2,
3)

```

which should produce the needed result.

Anything against using `transpose()`?

You can also use multiline comments `#= ... =#` to eliminate the line break, e.g.

```julia
x = [1 2 3 #=
  =# 4 5 6]

```

I was wondering about it, but I was looking for a more clean solution.  
Thank you by the way, this solves the problem as well
