Scripting Guide for OpenMatrix Language
OpenMatrix is a mathematical scripting language.
Literals
Literals are items that are constant throughout the life of the application. Literals include numeric, imaginary, characters,
strings, logicals, and Other (NaN/Inf).
Other Literals
Inf and NaN are two special literals predefined in the OpenMatrix language.
Collections
A collection is an ordered grouping of elements (which may be literals or other collections).
Identifiers
Identifiers are user-ascribed names that can refer to literals, other identifiers, or functions.
Numerics
Numeric literals come in the form of a scalar, integer, decimal, or scientific notation (exponential).
Imaginary
Imaginary literals are numeric literals followed immediately by one of the characters that represents the imaginary constant
i (defined as the square root of -1).
Strings
String literals are specified by a sequence of characters between ' (single quote) characters.
Data Types
Data types are items that are constant throughout the life of the application and are built into the OpenMatrix language.
Strings
Strings are arrays of characters.
Variables and Assignments
OML language scripts manipulate data through variables. Variables are referred to by their name (alphanumeric) and can be created
(assigned) and deleted as described in this section.
Indexing
Indexing is used to retrieve one or more specific values out of a collection.
Operators
Operators are used to combine operands.
Operator Descriptions (tables)
Each operator in this section is explained with the operations of scalars, vectors, and matrices that are allowed for
said operator.
Expressions and Statements
Statements are made of expressions and may be a simple expression or a more complex variety of expressions.
Flow of Control and Looping
Loops are used to perform the same set of statements multiple times.
Workspace and Scoping Rules
There are two types of workspaces: Local and Global.
Functions
Functions are packets of statements that can be used repeatedly.
Scripts and Functions
OpenMatrix statements persist in .oml files.
Files
This section describes files that can be manipulated by the OpenMatrix Language.
Error and Warning Messages
Errors and warning messages are both output in the console (or the Command Window in GUI mode) of Activate .
Objects in OpenMatrix Language
Objects in OML are defined using the classdef keyword. This creates a blueprint for an object but does not actually create (instantiate) anything.
Reference Guide for OpenMatrix Language Functions
The Reference Guide contains documentation for all functions supported in the OpenMatrix language.
Block Reference Guide
Describes all of the blocks in the installed Activate library.
Glossary
Key terms associated with the software.
Keyboard Shortcuts
Define shortcuts to common operations.
Literals
Literals are items that are constant throughout the life of the application. Literals
include numeric, imaginary, characters, strings, logicals, and Other (NaN/Inf).
