In mathematics, a function on the real numbers is called a step function if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant function having only finitely many pieces.
In Mathematics, a step function (also called as staircase function) is defined as a piecewise constant function, that has only a finite number of pieces. In other words, a function on the real numbers can be described as a finite linear combination of indicator functions of given intervals.
The Heaviside step function, or the unit step function, usually denoted by H or θ (but sometimes u, 1 or 𝟙), is a step function named after Oliver Heaviside, the value of which is zero for negative arguments and one for positive arguments.
A function on the reals R is a step function if it can be written as a finite linear combination of semi-open intervals [a,b) subset= R. Therefore, a step function f can be written as f(x)=alpha_1f_1(x)+...+alpha_nf_n(x), where alpha_i in R, f_i(x)=1 if x in [a_i,b_i) and 0 otherwise, for i=1, ..., n.
In calculus, the step function, also known as the Heaviside function, is a piecewise-defined function that changes its value abruptly at a specific point. The step function is denoted by \(H(x)\) and is defined as: \(H(x) = \begin{cases} 0, & \text{if } x < 0 \\ 1, & \text{if } x \geq 0 \end{cases}\)
In mathematics, a step function refers to a finite linear combination of indicator functions of given intervals. Step Function is also known as the Greatest Integer Function or Floor Function. We can also come in contact with step functions while dealing with other types of functions.
In this section we introduce the step or Heaviside function. We illustrate how to write a piecewise function in terms of Heaviside functions. We also work a variety of examples showing how to take Laplace transforms and inverse Laplace transforms that involve Heaviside functions.
A step function (or staircase function) is a piecewise function containing all constant "pieces". The constant pieces are observed across the adjacent intervals of the function, as they change value from one interval to the next. A step function is discontinuous (not continuous).

As the name suggests, a step function is sometimes called the staircase function. We can also define it as the constant function on the real numbers. It is a piecewise constant function on the finite set.
