Regulated function

In the context of mathematical analysis, a **regulated function** typically refers to a function that is defined on an interval (often the real numbers) that satisfies certain continuity-like properties. Specifically, the term is most commonly associated with functions that are piecewise continuous and have well-defined limits at their points of discontinuity. Regulated functions can be thought of as functions that are "well-behaved" despite having discontinuities. They can often be expressed as the limit of sequences (e.g.
