Ok, that’s much cleaner than my SVector variant. Forget my code and use this if you can live with the transposed memory layout.
But could I use multiple keys with that method?
You can use the by or lt options to specify the sorting criteria, e.g.
sort(Atup; alg=QuickSort, by=x->(x[3],x[1],x[2]))
will sort by the 3rd column, the 1st column, then the 2nd column (since tuples are compared by lexicographic order of the elements)

I’ve used that format for the sortrows function but it doesn’t seem to work with the sort function.
what format? It worked using @sdanisch’s example.
