Description. Methods of Numerical Approximation is based on lectures delivered at the Summer School held in Septemberat Oxford University. The book deals with the approximation of functions with one or more variables, through means of more elementary Edition: 1. This book presents numerical approximation techniques for solving various types of mathematical problems that cannot be solved analytically.

In addition to well-known methods, it contains a collection of non-standard approximation techniques that appear in the literature but are not otherwise well known.

This text also contains original methods developed by the author. Ideal as a course text in numerical analysis or as a supplementary text in numerical methods, A Survey of Numerical Mathematics judiciously blends mathematics, numerical analysis, and computation.

The result is an unusually valuable reference and learning tool for modern mathematicians, computer scientists, programmers, engineers, and physical 4/5(1). OCLC Number: Description: xvi, pages: illustrations ; 24 cm: Contents: Motivation for working in numerical analysis --Classical numerical analysis --The constructive theory of functions --Automatic computers --Use and limitation of computers --Matrix computations --Numerical methods for finding solutions of nonlinear equations --Eigenvalues of finite matrices --Numerical methods.

Economised approximation formulas can provide the required accuracy with less numerical operations, and can make numerical algorithms faster, especially when such formulas are nested in loops. The other important use of approximation is in calculating functions that are defined by values at a chosen set of : boris Obsieger.
