A list in the hp 39g+ is the same mathematically as a set. As with a set, it is

written as numbers separated by commas and enclosed with curly brackets.

Eg. {2,5,-2,10,3.75}

The list variables

Using the HOME view these lists can be stored

in special list variables. There are ten of these

L1,L2,..L9,L0.

Eg. {2,5,-2,10,3.75} L1

Operations on lists

Typing L1 and then ENTER will then retrieve

the list. Lists can also be multiplied by a

constant and have a constant added to them

(see below)

If we store another list of the same length into L2, then the two lists can be

multiplied together. The resulting list is obtained by multiplying each element

in the first list by the matching element in the second list.

Many of the normal mathematical functions also work on lists of numbers by

performing the operation on each individual element. Lists on the hp 39g+

can contain more than simply numbers. For example, the return value for

some matrix functions is a list where each element is a matrix. Elements of a

list can be matrices, lists and other things..

Statistical columns as lists

The column variables C1,C2..C9,C0 in the

Statistics aplet are actually list variables

attached to their aplet and can be used as

extra storage if you need more list variables.

The statistical variables have the additional

advantage, of course, that they can be

graphed in the Statistics aplet and with all the

usual statistical analysis measures available.

To transfer a list variable to a statistics

variable, just store one into the other (see

right). As you can see in the second view, the

list has been transferred to C1. Pressing

would now give the usual

statistical measures for the newly created column.
