A step function is constant on each member of a finite or countable measurable partition of its domain. Indicator functions of measurable sets are basic examples.

A step function is a type of piecewise function that changes its value at specific intervals, resulting in a graph that looks like a series of steps. These intervals can be defined by any rules, leading to a function that stays constant over each interval before jumping to a new value at the boundaries. ### Key Characteristics of Step Functions: 1. **Piecewise Definition**: A step function can be defined using different constant values over different ranges of the input variable.
