Function
In general (not in the mathematical but in the engineering sense), a function is a goal-oriented property of an entity. Function (according to the TOGA meta-theory, A.M. Gadomski, 1993) is not a physical property of a system, it depends how this system (a distinguished process) is used. The carrier of a function is a process; therefore, the same function is possible to realise using different physical processes, and one process can be a carrier of different functions. For example, clock main function, i.e. a presentation of time, can be realized by different physical processes, such as, atomic, electronic, mechanical or water movement. In natural language, the concept function is frequently mixed with process or task.
Function may refer to:
- The role of a component in an assembly, or of an element in a systemic aggregate (such as a person within a group)
- (In mathematics)
- The fundamental concept of a mathematical function
- A functional
- (In computer science)
- A function subprogram that is a constituent element of a program written in a functional programming language, often analogous to a mathematical function
- A subroutine or procedure that normally computes a value
- In object-oriented programming, a function object
- In sociology, the focus of functionalism: social function
- In music, diatonic functionality
