type your single variable in. say F1
@HOME or CAS
type F1(2i);
F1({1,2,3,3+3i, 4i}) to build a table

That is what I was looking for. Slightly clunkier than what I was used to in the CASIO.
The numeric mode should support displaying tables of complex valued outluts, and so should plotting, as well.
Is there a way to set the unused touch menus @home or @cas to custom functions in the HP Prime? Most of the touch row is completely unused when typing, I can think of a lot of useful things that could be put there.
