Hello! I have a simple query about concatenating ranges into a row matrix. The desired output is

```julia
[0 1 2 3 4]

```

which I am trying to achieve with

```julia
[[(1 - 1):0]' [1:5-1]']

```

However, the output I receive is

```julia
1×2 adjoint(::Vector{UnitRange{Int64}}) with eltype Adjoint{Int64, UnitRange{Int64}}:
 [0;;] [1 2 3 4]

```

Can someone help me with the correct syntax?

</div>

```julia
julia> [((1 - 1):0)' (1:5-1)']
1×5 adjoint(::Vector{Int64}) with eltype Int64:
 0 1 2 3 4

# or

julia> [(1 - 1):0; 1:5-1]'
1×5 adjoint(::Vector{Int64}) with eltype Int64:
 0 1 2 3 4

```

This

```julia
[(1 - 1):0]'

```

is a vector containing a vector, which is not what you want

Thank you so much @baggepinnen

May I please ask what the outer brackets in `( (1 - 1):0 )` achieve?

They make sure that the `'` applies to the range rather than to the last element of the range

This form results in a Matrix{Int64}: and not a adjoint(::Vector{Int64}) .

```julia
[((1 - 1):0);; (1:5-1)']
[((1 - 1):2)';; (3:5-1)']

```
