👉 In mathematics, interpolatory functions are a type of function that is defined by linear interpolation. They are commonly used in computer graphics and computer-aided design (CAD) software to represent a continuous curve or surface as a series of segments. Interpolatory functions are also known as spline functions, which are named after the mathematical concept of spline curves, which are smooth, piecewise-linear continuous functions that can be defined parametrically. Interpolatory functions are used in CAD software applications to create
