附件1是关于FFT算法的详细编程，及详细原理讲解，个人认为，这篇论文对从事信号处理，频谱分析很有帮助，特使是进一步理解FFT算法，很有必要阅读。 程序+原理+运行！ 附件2是关于直接运行FFT工具箱进行频谱分析，请大家可以参考对照，对理解FFT算法肯定有帮助！ (matalb fft 频谱分析)

说明：  一个很好的MIMO的信道模型程序，很实用。 没有密码，可以自由下载(A very good MIMO channel model program, it is practical. No password, you can free download)

说明：  这个程序能够显示EMD分解后的图形进行三维显示。(This program can display EMD decomposition of three-dimensional graphics display.)

基于Matlab H inf 鲁棒控制的设计 简述了 鲁棒控制器的基本思想,给出了运用Matlab鲁棒控制工具箱为假定空间桁架设计 鲁棒控制器的设计过程,同时也给出了控制器作用下闭环系统的分析结果(Robust control based on Matlab H inf robust controller design outlines the basic idea, given the use of Matlab robust control toolbox to assume that space truss design robust controller design process, but also gives the controller closed-loop system under analysis)

The Laplacian Pyramid as a Compact Image Code的reduce函数的matlab仿真(reduce function in the Laplacian Pyramid as a Compact Image Code is simulated in matlab )

DMC控制 当对系统知之甚少时用此方法 形成矩阵方程 并解此方程(DMC control when little is known about the system when using this method to form the matrix equation and solving this equation)

计算电磁学作业---1、对圆锥面进行划分网格；2、高斯消去法求解方程，都用matlab编写。含有报告和程序（在报告中，可以用）(Computational Electromagnetics job--- 1, the conical surface mesh 2, the Gaussian elimination method to solve equations, are written with matlab. Contains reports and procedures (in the report, can be used))

说明：  单极型倍频SPWM simulink仿真，和同等单极性SPWM相比，相同的开关频率，输出电压THD更低，逆变器输出可使用更小的滤波器，对逆变器体积的降低很有帮助，封装子系统，调制度、载波比和调制频率可自由调节，简单易用。matlab版本：2015b(Compared with the same unipolar SPWM, the same switching frequency and output voltage thd are lower. The output of the inverter can use smaller filters, which is very helpful to reduce the volume of the inverter. The package subsystem, modulation system, carrier ratio and modulation frequency rate can be adjusted freely and easy to use. Matlab version: 2015b)
