A Concise Introduction to Numerical Analysis
Douglas N. Arnold
Summary "A Concise Introduction to Numerical Analysis" by Douglas N. Arnold is a rigorous, proof-based textbook that explores the mathematical foundations, error bounds, and stability of algorithms used in scientific computing. Structured into six comprehensive chapters, the text moves from foundational approximation theory (such as polynomial interpolation and splines) and numerical integration to the direct and iterative methods of linear algebra, including matrix factorizations and error conditioning. It then covers iterative techniques for solving nonlinear systems and optimization problems, before concluding with detailed mathematical frameworks for solving differential equations using one-step, multi-step, finite difference, and finite element methods. Throughout, Arnold emphasizes a highly theoretical approach, analyzing every computational method through the critical lenses of accuracy, efficiency, and stability against floating-point errors.
