说明：  这是一篇关于多用户下行链路预编码的文章，主要是从一些基本的矩阵变换以及矩阵运算方面讲解一些原理，最后给出仿真实验

Matlab R14 brief introduction

matlab画三个纵坐标源码,源码中有三维纵坐标的例子。(matlab draw three ordinate source, the source code is an example of a three-dimensional ordinate.)

基于改进滑模频率偏移法的光伏孤岛检测研究(PV islanding detection based on improved sliding mode frequency offset)

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)

仿真效果非常好，本科毕设要求参见标准测试模型，脉冲响应的相关分析算法并检验。( Simulation of the effect is very good, Undergraduate complete set requirements refer to the standard test models, Related impulse response analysis algorithm and inspection.)
