Numerical analysis From Scholarpedia Kendall E. Atkinson (2007), Scholarpedia, 2(8):3163. doi:10.4249/scholarpedia.3163 revision #61617 [ link to/cite this article Curator: Dr. Kendall E. Atkinson, Department of Computer Science, Department of Mathematics, University of Iowa Numerical analysis is the area of mathematics and computer science that creates, analyzes, and implements algorithms for solving numerically the problems of continuous mathematics. Such problems originate generally from real-world applications of algebra, geometry, and calculus, and they involve variables which vary continuously. These problems occur throughout the natural sciences, social sciences, medicine, engineering, and business. Beginning in the 1940's, the growth in power and availability of digital computers has led to an increasing use of realistic mathematical models in science, medicine, engineering, and business; and numerical analysis of increasing sophistication has been needed to solve these more accurate and complex mathematical models of the world. The formal academic area of numerical analysis varies from highly theoretical mathematical studies to computer science issues involving the effects of computer hardware and software on the implementation of specific algorithms. Contents Areas of numerical analysis Systems of linear and nonlinear equations Approximation theory Numerical solution of differential and integral equations ... edit Areas of numerical analysis A rough categorization of the principal areas of numerical analysis is given below, keeping in mind that there is often a great deal of overlap between the listed areas. In addition, the numerical solution of many mathematical problems involves some combination of some of these areas, possibly all of them. There are also a few problems which do not fit neatly into any of the following categories.

Residual (numerical analysis) From Wikipedia, the free encyclopedia Jump to: navigation search For other senses of the word "residual" in mathematics, see residual (mathematics) Loosely speaking, a residual is the error in a result. To be precise, suppose we want to find x such that Given an approximation x of x , the residual is whereas the error is If we do not know x , we cannot compute the error but we can compute the residual. edit Residual of the approximation of a function Similar terminology is used dealing with differential integral functional equations . For the approximation of the solution of the equation T f x g x the residual can either be the function or can be said to be the maximum of the norm of this difference over the domain , where the function is expected to approximate the solution , or some integral of a function of the difference, for example, In many cases, the smallness of the residual means that the approximation is close to the solution, i.e., In these cases, the initial equation is considered as well-posed ; and the residual can be considered as a measure of deviation of the approximation from the exact solution.
