最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)

说明：  simulink工具箱的入门PPT讲解，有附带m文件，强烈推荐(simulink toolbox PPT talks, with m files are strongly recommended)

相干光通信的matlab离线处理代码，非常有用的资料。。。。(Coherent optical communications offline processing matlab code, very useful information. . . .)

this code is for dpl network .this code runs for realtime ................................

不同方法估计协方差矩阵的Capon波束形成,以及多点约束的Capon波束形成和方向图，自己运行效果很好。(Different methods of estimation covariance matrix Capon beamforming, and multi-point constraints Capon beamforming and direction maps, run their own good results.)

matlab 的 am和dsb调制 先你得介绍 am 的调制的基本原理，解调的基本原理，这个书上肯定都有很多，你按照自己的理解重新再组织(Matlab am and DSB modulation first you have to introduce the basic principles of the AM modulation and demodulation of the basic principles, this book certainly has a lot of you according to their own understanding of re-organization)

包含微型计算机控制的案例，尤其以PID控制为主(microcomputer control)

说明：  电机仿真，MTPA控制策略，永磁同步电机(Motor simulation, MTPA control strategy, permanent magnet synchronous motor)
