@section MATRICES

@section OPERATORS
- MACSYMA uses the standard Mathematical operators:
! for Factorial,
!! for Double factorial,
^ or ** for Exponentiation,
* for Multiplication,
. for non-commutative multiplication
/ for Division,
+ for Addition, and
- for Subtraction.
In addition, it uses some other operators:
: for variable assignment (e.g. A:3 sets A to 3).
:= for function definition (e.g. F(X):=SIN(X) defines a function F).
Note: the term operator is used in either of two senses: syntactic
(meaning that it has special syntax properties in the MACSYMA
language) or semantic (referring to its functionality). In the
syntactic sense it is something which usually consists of
non-alphanumeric characters, e.g. "+" or "*" (exceptions include
"AND", "OR", and "NOT"). Semantically we sometimes refer to the
"operator of an expression", meaning that thing which is in the
operator part of the expression, such as the "+" in "A+B" or SIN in
"SIN(x)". Note: "+" in this latter example is also an operator in the
syntactic sense, whereas SIN is a mathematical function.
