Sorting Multiple Lists
You can specify more than one list when using
SortA(
and
SortD(
. In this case, the first list specified is the independent
one; any following lists are dependent.
The calculator sorts the independent list first, and then sorts
all the dependent lists by placing their elements in the same
order as their corresponding elements in the independent list.
This allows you to keep sets of related data in the same order
when you sort lists.
SortA(
indpntlist,dependlist1,dependlist2
)
SortD(
indpntlist,dependlist1,dependlist2
)
Define
L 2 ={3,4,7,9}
(independent),
L 3 ={1,2,3,4}
(dependent), and
L 4 ={14,13,12,11}
(dependent), and sort all three in descending
order.
1. Define
L 2 , L 3 ,
and
L 4
in the
List editor.
