Indicator function (convex analysis)

In the field of mathematics known as convex analysis, the indicator function of a set is a convex function that indicates the membership (or non-membership) of a given element in that set. It is similar to the indicator function used in probability, but assigns + ∞ {\displaystyle +\infty } instead of 0 {\displaystyle 0} to the outside elements.
