- Extended Definitions for Advanced Users
  PDF file with in-depth information on key topics in the User's Guide.
- 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).
  - Data Types
    Data types are items that are constant throughout the life of the application and are built into the OpenMatrix language.
    - Data Types
      Data types are items that are constant throughout the life of the application and are built into the OpenMatrix language.
    - Complex
      The Complex data type uses imaginary literals.
    - Double
      The double data type uses numeric literals.
    - Strings
      The string data type involves a sequence of characters and uses string literals.
    - Structures
      Structures are a data type similar to cells. However, where cells use numeric indices to refer to specific pieces of data, structures use strings.
    - Cell Arrays
      Cell arrays are generic data containers.
    - Multidimensional Matrices
      OML supports multidimensional matrices.
    - Sparse Matrices
      Sparse matrices are a special case of 2D matrices, where only non-zero elements are stored and displayed for efficiency. A sparse matrix typically has a high percentage of zero elements.
  - 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, which may be simple or complex.
  - 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.
  - Plotting and Visualization
    Create 2D and 3D plots and control their style and appearance.
  - 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.
- Function Guide for Activate
  Provides information about developing and simulating models through the Activate Application Program Interface.
- Glossary
  Key terms associated with the software.
