In mathematics, an indicator function or a characteristic function of a subset of a set is a function that maps elements of the subset to one, and all other elements to zero. That is, if A is a subset of some set X, one has $${\displaystyle \mathbf {1} _{A}(x)=1}$$ if $${\displaystyle x\in A,}$$ Meer weergeven The indicator function of a subset A of a set X is a function defined as The Iverson bracket provides the equivalent notation, $${\displaystyle [x\in A]}$$ or ⟦x ∈ A⟧, to be … Meer weergeven The notation $${\displaystyle \chi _{A}}$$ is also used to denote the characteristic function in convex analysis, which is defined as if using the reciprocal of the standard … Meer weergeven In classical mathematics, characteristic functions of sets only take values 1 (members) or 0 (non-members). In fuzzy set theory, characteristic functions are generalized to take value in the real unit interval [0, 1], or more generally, in some algebra Meer weergeven 1. ^ The Greek letter χ appears because it is the initial letter of the Greek word χαρακτήρ, which is the ultimate origin of the word … Meer weergeven The indicator or characteristic function of a subset A of some set X maps elements of X to the range $${\displaystyle \{0,1\}}$$.
