线性方程组，非线性方程组，最小二乘拟合等数值算法的matlab实现。(Linear equations, nonlinear equations, numerical algorithm such as least-squares fitting of the realization of matlab.)

本章将介绍 Hitech-PICC 编译器的一些基本概念，由于篇幅所限将不涉及C 语言的标准 语法和基础知识介绍，因为在这些方面都有大量的书籍可以参考。重点突出针对PIC 单片 机的特点而所需要特别注意的地方。(This chapter will introduce the Hitech-PICC compiler of some basic concepts, lack of space will not be involved in the standard C language to introduce basic knowledge of grammar and because in these areas can have a large number of reference books. Focused features for the PIC MCU and the need of special attention.)
