基于动态切换函数的动态滑模控制，二阶系统仿真(Dynamic sliding mode control based on dynamic switching function，The second order system simulation)

计算单个球型粒子的的粒子光强分布，对比不同折射率条件下粒子的光强分布(A particle for calculating a single spherical particle of light intensity distribution)

用C语言编写的IEEE34节点系统画图例程，用于matlab(the graghing programme of IEEE34 node system written in C, for matlab )

用matlebl进行的通信原理的仿真，讲解透彻，希望对大家有帮助(The simulation of the communication matlebl principle, to explain thoroughly, we hope to help)

主要包括图像的中值、均值去噪、非局部均值、分块局部去噪算法；还有均方误差和峰值信噪比评价、以及matlab基础学习资料如边缘检测、小波变化、灰度值转换等(Including image median, mean denoising, non-local means, block local denoising algorithm also mean square error and peak signal to noise ratio evaluation, and matlab based learning materials such as edge detection, wavelet transform, gray scale value conversion wait)

matlab动态模拟程序例子，小电风扇，是学习matlab的很好实例。(Dynamic simulation program matlab example, a small fan, is a good example to learn matlab.)

这本电子书的名字是"基于matlab_simulink的系统仿真技术及应用"，同样对于学习通信的人士来说挺不错的，但是用的时候请下载超星阅览器(This e-book name is " based on matlab_simulink System Simulation Technology and Application" , on the same people who have to learn to communicate quite well, but when used, download SSReader)

说明：  数字信号处理中，分别用重叠相加法和重叠保留法求两个序列的线性卷积，并对两种方法的结果进行比较。两种方法的结果是相同的。(Digital signal processing, respectively, and overlap with the overlap-add method to retain Method linear convolution of two sequences, and the two methods were compared. Two results are the same.)
