| 本书介绍了现代数值近似技术的理论及实用知识，解释了它们的工作原理。同它的前几个版本一样，该书仍将重点放在近似技术的数值分析上，以便为读者今后的学习打下坚实的数值分析与科学计算基础。本书内容丰富、翔实，可以根据不同的学习对象和学习目的，选择、组织、串联相应的章节，形成侧重于理论或是侧重于实用的两种学习策略。书中的每个概念均以大量的例子说明，同时书中还包含2000多个习题，范围从方法、算法的基本应用到理论的归纳与扩展，涉及物理、计算机、生物、社会科学等多个不同的领域。通过这些实例，进一步说明在现实世界中，数值方法是如何被应用的。第七版新增了两个突出的部分，一是前承条件共轭梯度方法，为线性方程系统提供了更完备的解决方法；另一部分是同伦与连续方法，为非线性方程系统的近似求解提供了不同的方法。 |
