Lists 16-7

CONCAT(L1,L2). An argument can be either a list

variable name (such as L1) or the actual list. For

example, REVERSE({1,2,3}).

• If Decimal Mark in Modes is set to Comma, use

periods to separate arguments. For example,

CONCAT(L1.L2).

Common operators like +, –, ×, and / can take lists as

arguments. If there are two arguments and both are lists,

then the lists must have the same length, since the

calculation pairs the elements. If there are two arguments

and one is a real number, then the calculation pairs the

number with each element of the list.

Example

5*{1,2,3} returns {5,10,15}.

Besides the common operators that can take numbers,

matrices, or lists as arguments, there are commands that

can only operate on lists.

CONCAT Concatenates two lists into a new list.

CONCAT(list1,list2)

Example

CONCAT({1,2,3},{4}) returns {1,2,3,4}.

LIST Creates a new list composed of the first differences, that

is, the differences between the sequential elements in

list1. The new list has one fewer elements than list1. The

first differences for {x

... x

} are {x

–x

... x

–x

n–1
