于慧敏信号与系统第二版第七章部分习题的matlab代码... (Number in Huimin Xin Chapter VII of the system part of the second edition of Exercise matlab code ...)

Transforming images from the spatial domain to frequency domain using FFT and DCT, also it includes transforming to the Cepstrum domain.

时域有限差分法的2维代码~~~~很详细的，大家可以看看~~~~(Finite-difference time-domain 2 dimensions of the code )

用小波默认阈值法对散斑图进行去噪，还包括用相移法和最小二乘法求相位及去包裹(wavelet denoising used in speckle pattern)

分别实现由MVDR和RLS实现了单波束形成（signal beamfroming using MVDR and RLS）(Were implemented by MVDR and RLS achieve a single beam forming (signal beamfroming using MVDR and RLS))

改进的背景差分法，结合了背景差分法和帧间差分法的优点，能更好的进行视频处理。(Improved background subtraction method, combining the advantages of the background difference and frame difference method, and better video processing.)

基于MATLAB/simulink搭建的应用于永磁同步电机（PMSM）的无传感器控制，主要是基于矢量控制，采用滑模转速和转子位置观测器取代传统的位置传感器，最终实现对PMSM的控制(The sensorless control based on MATLAB/simulink for permanent magnet synchronous motor (PMSM) is mainly based on vector control. Instead of the traditional position sensor, the sliding mode speed and rotor position observer are used to control the PMSM.)

very useful robust control codes in matlab.

基于元胞自动机编写的传染病扩散matlab代码，为了运行方便，把所有代码都集中在了一个m文件中，重要部分都带有注释，算法取得了较好的结果，在这里分享给大家。( Cellular Automata based infectious disease diffusion write matlab code, in order to facilitate operation, all the codes are concentrated in an m file, important parts are annotated, the algorithm has achieved good results, here for everyone to share.)
