The easiest way is to use `writedlm`, but that won’t give you the exact same formatting:

```julia
using DelimitedFiles
p = [1, 2]
q = [3, 4]
writedlm("pqfile.txt", (p, q), " ")

# Output:
# 1 2
# 3 4

```

If you want more control over the formatting you can write the file manually using the `@printf` macro and iterating over the arrays.
