principal component matlab code.

实现均匀pcm编码的matlab函数，可以把波形转换为PCM编码(Matlab code for uniform pcm function can be converted to PCM encoded waveform)

说明：  用面包师算法进行图像的置乱，首先是将图像分为4个部分，对每一个部分采用不同的变换方法(With baker image scrambling algorithm, first the image is divided into four parts, each part of the transformation method using different)

说明：  mosek算法教程+实例，内含工具箱和pdf介绍(MOSEK algorithm tutorial + examples, including toolbox and PDF introduction)

本程序峭度的计算程序，已做成工具包，可以直接调用(The program kurtosis calculation program, has made kit, you can call)

基于Matlab直线法分析同轴线电磁场分布(Matlab Analysis of the straight-line method based on electromagnetic field distribution of coaxial line)

ofdm基带传输，信道编码，QPSK调制，卷积编码(the OFDM baseband transmission, channel encoding, QPSK modulation, convolutional encoder)

说明：  应用于多峰值MPPT问题，采用PSO寻找最大功率点，具体实现在S-function中，仿真时建议找一个内存大的电脑用连续仿真，离散在这种仿真时容易出问题。自行读程序只需输入光伏电压电流即可实现，仿真多峰值问题时光伏板注意反并联二极管，输出为占空比，boost、隔离boost都可以使用(For multi-peak MPPT problem, PSO is used to find the maximum power point, which is realized in S-function. It is suggested that a computer with large memory be used for continuous simulation. Discrete simulation is prone to problems. The self-reading program can be realized only by inputting photovoltaic voltage and current. In the simulation of multi-peak problem, the photovoltaic board pays attention to the anti-parallel diode.)
