In numerical analysis, numerical integration constitutes a broad family of algorithms for calculating the numerical value of a definite integral, and by extension, the term is also sometimes used to describe the numerical solution of differential equations.
This article focuses on calculation of definite integrals.
Description
The term numerical quadrature (often abbreviated to quadrature) is more or less a synonym for numerical integration, especially as applied to one-dimensional integrals.
Some authors refer to numerical integration over more than one dimension as cubature; others take quadrature to include higher-dimensional integration.
