Editing Maple (software) (section)

===Architecture===
Maple is based on a small [[kernel (operating system)|kernel]], written in [[C (programming language)|C]], which provides the Maple language. Most functionality is provided by libraries, which come from a variety of sources. Most of the libraries are written in the Maple language; these have viewable source code.  Many numerical computations are performed by the [[NAG Numerical Libraries]], [[Automatically Tuned Linear Algebra Software|ATLAS]] libraries, or [[GNU Multi-Precision Library|GMP]] libraries.

Different functionality in Maple requires numerical data in different formats. Symbolic expressions are stored in memory as [[directed acyclic graph]]s. The standard interface and calculator interface are written in [[Java (programming language)|Java]].
