中文说明：
精通matlab6.5版_数值计算本章将花较大的篇幅讨论若干常见数值计算问题：线性分析、一元和多元函数分析、微积分、数据分析、以及常微分方程（初值和边值问题）求解等。但与一般数值计算教科书不同，本章的讨论重点是：如何利用现有的世界顶级数值计算资源 MATLAB。至于数学描述，本章将遵循“最低限度自封闭”的原则处理，以最简明的方式阐述理论数学、数值数学和 MATLAB计算指令之间的内在联系及区别。
English Description：
Proficient in MATLAB6.5_ Numerical calculation this chapter will devote a large amount of space to discussing some common numerical calculation problems: linear analysis, univariate and multivariate function analysis, calculus, data analysis, and the solution of ordinary differential equations (initial value and boundary value problems). However, different from the general numerical calculation textbooks, this chapter focuses on how to use the existing world-class numerical calculation resource MATLAB. As for mathematical description, this chapter will follow the principle of "minimum self closure", and explain the internal relations and differences among theoretical mathematics, numerical mathematics and matlab calculation instructions in the most concise way
