Chapter 11: Lists 169
With two or more lists,
SortA( and SortD( sort keylistname, and then sort each dependlist by placing its
elements in the same order as the corresponding elements in
keylistname. All lists must have the
same dimension.
SortA(keylistname,dependlist1[,dependlist2,...,dependlist n])
SortD(keylistname,dependlist1[,dependlist2,...,dependlist n])
Note:
• In the example, 5 is the first element in L4, and 1 is the first element in L5. After SortA(L4,L5), 5
becomes the second element of
L4, and likewise, 1 becomes the second element of L5.
• SortA( and SortD( are the same as SortA( and SortD( on the STAT EDIT menu (Chapter 12).
• You cannot sort a locked list.
Using dim( to Find List Dimensions
dim( (dimension) returns the length (number of elements) of list.
dim(list)
Using dim( to Create a List
You can use
dim( with ¿ to create a new listname with dimension length from 1 to 999. The
elements are zeros.
length!dim(listname)
Using dim( to Redimension a List
You can use
dim with ¿ to redimension an existing listname to dimension length from 1 to 999.
• The elements in the old
listname that are within the new dimension are not changed.
• Extra list elements are filled by 0.
• Elements in the old list that are outside the new dimension are deleted.
