Matrix Functions
There are two categories of matrix operations: functions and
commands. The matrix functions are given in the following
table. The matrix commands are for programming; they
appear in chapter 8, Programming.

Conventions
• Functions can be used in any aplet or in Home. They are
listed in the MATH menu under the Matrix category. They
can be used in mathematical expressions—phmonVy in
Home, 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. Example:
CROSS {vector!, vector2). The matrix input can be either
a matrix variable name (such as Ml) or the actual matrix
data inside brackets. For example, CROSS (Ml, [ 1 , 2 ] ) .
• If Decimal Mark In MODES is set to Comma, use periods to
separate arguments. For example,
CROSS {vector! ,vector2).
Commands are limited to programs. Matrix commands are
listed in the MATH menu ([ math ] {{ cmds }}), category Matrix.
9 For rom^ or column* supply the number of the row
(counting from the top, starting with 1) or the number of
the column (counting from the left, starting with 1).
9 The arguments matrix and matrixnarne can refer to either a
vector or a matrix.
