A USEFUL BOOK TO UNDERSTAND THE BASICS OF ELECTRONICS AND ELECTRICAL CIRCUITS

Matlab中没有现成的Lagrange插值函数，必须编写一个M文件实现Lagrange插值。 设n个节点数据以数组x0,y0 输入（注意Matlat的数组下标从1开始），m 个插值点以数组 x输入，输出数组y 为 m个插值。 编写一个名为lagrange.m的M文件。(Matlab is not off-the-shelf Lagrange interpolation function, we must realize the preparation of an M file Lagrange interpolation. N nodes based data to an array of x0, y0 input (Note Matlat subscript of the array starting at 1), m a x interpolation points to the array input and output array y for m months interpolation. Lagrange.m the preparation of a M-file.)

该程序主要用于损伤梁的模态计算，包括特征多项式和计算的详细过程。(The program is mainly used for the modal calculation of the damaged beams, including the characteristic polynomial and computing process.)

使用sift算法，可以完成两张图片的拼接(stich two image with sift algorithm)

在普通的移动机器人基于多智能体一致性的编队控制实验的基础上，增加了事件触发机制和一个虚拟领导者模型以达到更好的控制效果。(Based on the formation control experiments of common mobile robots based on multi-agent consistency, an event triggering mechanism and a virtual leader model are added to achieve better control effect.)

to compares two least-square linear regression

CDMA中Rake接收机源码，在Matlab环境下运行(Rake receiver in CDMA source, in the Matlab environment running)

利用时域相关定理结合FFT完成相关函数计算源程序，包括时延估计。(Theorems time domain and FFT to complete the correlation function computing source, including delay estimation.)

说明：  抽象类以及纯虚函数的相关笔记。Figure作为基类，派生出Circle，Square(Abstract classes and pure virtual functions related notes. Figure as a base class, derived Circle, Square)
