Components of the Sym application

The three main components of the Sym application are the content, the tools used to edit and manage the content and the libraries that provide the objects and functionality that are used to create and edit expressions.

The content can include Document modules that are the primary containers for content in the document. In addition, a document can include Object modules which are used to create new symbolic objects. These objects can be either intended to be used in mathematical expressions or they can be functions used the Sym code. In addition, a document can contain Unit test modules that are used to test functions defined in Sym.

The tools include the Document Explorer that provides a tree view of the current document and lets you manage the modules, references and libraries in the document. A Find and Replace window and a number of other tools described in the Tools section of the documentation.

The libraries include Basic and Core libraries that set the foundations for other libraries. The Math, Trig and Calc libraries include objects and functionality to allow creating expressions for basic mathematics.
