174 Functions and commands

.* List or matrix multiplication symbol. Returns the term-by-term

multiplication of two lists or two matrices.

List1.*List2 or Matrix1.*Matrix2

Example:

[[1,2],[3,4]].*[[3,4],[5,6]] gives

[[3,8],[15,24]]

./ List or matrix division symbol. Returns the term-by-term division

of two lists or two matrices.

.^ Returns the list or matrix where each term is the corresponding

term of the list or matrix given as argument, raised to a power.

List.^Integer

or Matrix.^Integer

/ Division symbol. Returns the quotient of two numbers, or the

term by term quotient of two lists. For division of a matrix by

a square matrix, returns the left-multiplication by the inverse of

the square matrix.

:= Stores the evaluated expression in the variable. Note that:=

cannot be used with the graphics variables G0–G9. See the

command BLIT.

var:=expression

Example:

A:=3 stores the value 3 in the variable A

< Strict less-than-inequality test. Returns 1 if the left side of the

inequality is less than the right side, and 0 otherwise. Note

that more than two objects can be compared. Thus 6 < 8 <

11 returns 1 (because it is true) whereas 6 < 8 < 3 returns 0

(as it is false).

<= Less than or equal inequality test. Returns 1 if the left side of

the inequality is less than the right side or if the two sides are

equal, and 0 otherwise. Note that more than two objects can

be compared. See comment above regarding <.

<> Inequality test. Returns 1 if the inequality is true, and 0 if the

inequality is false.

= Equality symbol. Connects two members of an equation.

== Equality test. Returns 1 if the left side and right side are equal,

and 0 otherwise.
