External functions

External An external function is an object of the D2000 system, that allows to extend extending the standard set of functions that are comprised in the mathematical apparatus. The External function object represents an exported function in a dynamically linked library (file). When properly implemented, they allow to substitute (in some cases also simplify) system extensions implemented by the interfaces D2000 ObjApi or D2000 KomAPI.

Creation The creation of an External function consists of two steps:

• Implementation of a function within a dynamically linked library,
• Definition of an object of External function type.
