Are you looking for

```julia
julia> a = [7 0 4 6 2 3 9]
1×7 Matrix{Int64}:
 7 0 4 6 2 3 9

julia> sort!(a, dims = 2)
1×7 Matrix{Int64}:
 0 2 3 4 6 7 9

```

Your array is `1x7` as you see, so the dimension you want to sort along is the second.

Hi – you should use commas

```julia
julia> b = [7, 0, 4, 6, 2, 3, 9]
julia> sort(b)

```

In Julia, the usual vector is a column vector, and row vectors (what you get when there is a space between numbers rather than a comma) are as @nilshg said.
