👉 Cubature is a mathematical technique used in numerical analysis to approximate the value of an integral. It involves finding a finite sum that approximates the area under a curve or surface, and then taking a limit as this sum approaches zero. The process can be applied to various types of functions, including those involving multiple variables. In essence, cubature is a method for solving optimization problems in which one wants to minimize or maximize an objective function over a set of points. It involves finding the region that
