Question

Absolute beginner question here.
I have two lists in mathematica.
The first one was generated by the Table command:

Table[QP[[i]], {i, 10}]
which generates the list:

{52.5, 45., 37.5, 30., 22.5, 15., 7.5, 0., -7.5, -15.}

the second is a Range

Range[0, 9, 1]

which generates {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

I need to get these into a list of lists. i.e. {{0,52.5},{1,45} … } etc. But I can’t seem to get it. Do you need to use loops? Because I think that what I want can be generated with the Table and Array commands.

Thanks

The first parameter of Table can be any expression. You can have it output a list of lists, by specifying a list as the first parameter:

Table[{i-1, QP[[i]]}, {i, 10}]
(* {{0, QP[[1]]}, {1, QP[[2]]}, ... {8, QP[[9]]}, {9, QP[[10]]}} *)
