Opis

Theory and Applications of Numerical Analysis is a self-contained Second Edition, providing an introductory account of the main topics in numerical analysis. The book emphasizes both the theorems which show the underlying rigorous mathematics andthe algorithms which define precisely how to program the numerical methods. Both theoretical and practical examples are included.

• a unique blend of theory and applications
• two brand new chapters on eigenvalues and splines
• inclusion of formal algorithms
• numerous fully worked examples
• a large number of problems, many with solutions

Recenzje

"The first edition was an outstanding work, and the additions that have been put in the Second Edition are very appropriate and have been written up in exemplary fashion." --Philip J. Davis
