Function - Identity

About

An identity function is an algebraic law that defines when the output of the function is equal to the input.

Linear Algebra

identity function.

For any domain D: each domain element d map to itself:

<math>id_D : D \rightarrow D</math> Identity Function

Example

Addition (+) <MATH> x+0 = x </MATH>

Division: (/) <MATH> \frac{x}{1} = x </MATH>
