Step Function Approximation

Step Function Approximation is a mathematical technique in numerical analysis that belongs to the class of piecewise constant function approximations, distinguished by its use of disjoint subintervals over which the function takes constant values to approximate a more complex function, particularly in the construction of Riemann sums.
