掌握用MATLAB编写LU分解法与PLU分解法的程序；(The preparation of master LU decomposition method with MATLAB and the PLU decomposition procedure)

说明：  搭建了模电电路，实现仿真并得到仿真U I波形(The analog circuit is built, and the simulation UI waveform is obtained)

Matlab实用程序百例，一些简单的小程序，可以解决很多问题，好好研究必有所收获(Matlab utility hundred cases, some simple little program that can solve many problems, there must be a good study of the harvest)

实用matlab simulink搭建的风力发电机在孤岛运行条件下的仿真分析。(Wind turbines in the the island operation under the conditions of the simulation analysis.)

基于matlab平台，通过DCT算法来对视频进行压缩。代码包括视频分解成帧，DCT算法压缩，帧合成视频，以及综合的视频压缩M文件，可以直接仿真。有相应的图片，以及压缩前后的视频，还有原理word报告。(Based on matlab platform, through DCT algorithm to compress the video. Code includes video decomposition framing, DCT compression algorithm, frame composite video, and integrated video compression M files can be directly simulated. Corresponding images, and compressed video before and after, as well as the principle of word report.)

说明：  常规OFDM系统容易导致ICI，为了消除ICI，在信号传输前进行编码，本系统为1/2PCC编码，提高系统效率。(Conventional OFDM system easily lead to ICI, is encoded in the signal before transmission, in order to eliminate ICI, this system for 1/2PCC encoding to improve system efficiency.)

一些图像处理的小程序，有缩放，边缘提取，图像剪切等，希望对学习matlab图像初学者有所帮助(some small image processing procedures, zoom, edge extraction, image shear. hope to study images Matlab help beginners)

模拟声源在两种介质中产生的声波的传播，采用SPML作为吸收边界(we simulate the propagation of acoustic wave in two media. we use SPML as the boundary conditions.)

说明：  Gerchberg–Saxton（GS）算法是一种迭代算法，用于检索通过传播函数（如傅里叶变换）相关的一对光分布（或任何其他数学上有效的分布）的相位，前提是它们在各自光学平面上的强度已知。(The algorithm is an iterative algorithm for retrieving the phase of a pair of light distributions.)
