Bengt Fornberg

High-Accuracy Finite Difference Methods

• Gebundenes Buch

Produktbeschreibung

Finite differences are widely used for solving problems in scientific computing. One aspect underrepresented in textbooks concerns high-accuracy methods. Bengt Fornberg addresses that here. Full of conceptual insights, general perspectives, and practical considerations, it will be welcomed by graduate students, researchers, and educators.
