476 Matrices

Matrix functions and commands

Functions Functions can be used in any app or in Home view. They

are listed on the Math menu under the Matrix category.

They can be used in mathematical expressions—primarily

in Home view—as well as in programs.

Functions always produce and display a result. They do

not change any stored variables, such as a matrix

variable.

Functions have arguments that are enclosed in

parentheses and separated by commas; for example,

CROSS(vector1,vector2). The matrix input can be either a

matrix variable name (such as M1) or the actual matrix

data inside brackets. For example, CROSS(M1,[1 2]).

Menu format By default, a Matrix function is presented on the Math

menu using its descriptive name, not its common

command name. Thus the shorthand name TRN is

presented as

Transpose and DET is presented as

Determinant.

If you prefer the Math menu to show command names

instead, deselect the

Menu Display option on page 2 of

the

Home Settings screen (see page 26).

Commands Matrix commands differ from matrix functions in that they

do not return a result. For this reason, these functions can

be used in an expression and matrix commands cannot.

The matrix commands are designed to support programs

that use matrices.

The matrix commands are listed in the Matrix category of

the Commands menu in the Program Editor. They are also

listed in the Catalog menu, one of the Toolbox menus.

Press

D and tap to display the commands

catalog. The matrix functions are described in the

following sections of this chapter; the matrix commands

are described in the chapter Programming (see page

541).
