Operations with lists

Lists are a type of calculator’s object that can be useful for data processing and

in programming. This Chapter presents examples of operations with lists.

Definitions

A list, within the context of the calculator, is a series of objects enclosed

between braces and separated by spaces (#), in the RPN mode, or commas

(‚í), in both modes. Objects that can be included in a list are numbers,

letters, character strings, variable names, and/or operators. Lists are useful for

manipulating data sets and in some programming applications. Some

examples of lists are:

{ t 1 }, {"BET " h2 4}, {1 1.5 2.0},

{a a a a}, { {1 2 3} {3 2 1} {1 2 3}}

In the examples shown below we will limit ourselves to numerical lists.

Creating and storing lists

To create a list in ALG mode, first enter the braces key „ä (associated

with the + key), then type or enter the elements of the list, separating them

with commas (‚í). The following keystrokes will enter the list {1 2 3 4}

and store it into variable L1.

„ä 1 ‚í 2 ‚í 3 ‚í 4

™K~l1`

The screen will show the following:

The figure to the left shows the screen before pressing `, while the one to the

right shows the screen after storing the list into L1. Notice that before pressing

` the list shows the commas separating its elements. However, after pressing

`, the commas are replaced with spaces.

Entering the same list in RPN mode requires the following keystrokes:

„ä 1 # 2 # 3 # 4 `

~l1`K

1 2 ... 253 254 255 256 257 258 259 260 261 262 263 ... 886 887
