The study of algorithms that use numerical approximation for the problems of mathematical analysis is known as numerical analysis. Some of the major areas of study within this field are computing values of functions, interpolation, extrapolation, regression, optimization, evaluating integrals and differential equations. The major methods that are used in numerical analysis are direct and iterative methods. Direct methods compute the solution to a problem in a finite number of steps and are able to give the answer if they are performed in infinite precision arithmetic. Iterative methods form successive approximations that converge to the exact solution only in the limit. Numerical analysis is applied in all fields of physical sciences and engineering as well as in social sciences, medicine and life sciences. This book unravels the recent studies in the field of numerical analysis. The topics included herein on numerical analysis are of utmost significance and bound to provide incredible insights to readers. Those in search of information to further their knowledge will be greatly assisted by this book.
