POLSAR data reader in matlab

a numerical solution of Poisson equation for axis-symmetrical cylindrical coordinates

说明：  遗传算法整套源程序，包括初始种群，计算适应度值，选择，交叉变异等(Genetic algorithm source code package, including the initial population, calculation of fitness value, selection, crossover and other variant)

谐波分析 功率谱分析 交叉谱分析课程及例子(The harmonic analysis of power spectrum analysis courses and examples of the cross-spectral analysis)

Simulation Study on Four-quadrant Cascade Multilevel Inverter Based on AC Voltage Sensorless Simple Cell

帧差发源代码，来自matlab中文论坛，毕业设计需要(The frame difference originated code from Matlab Chinese Forum, graduation design needs)

说明：  本课题基于MATLAB平台的数字信号处理仿真演示系统。数字信号即离散信号，本设计带有一个丰富得GUI人机交互界面，一共包括4个部分，分别为：离散时间信号的卷积，基本函数的Z变换（单位阶跃信号，脉冲信号，斜变信号，正余弦信号，指数系列信号），Z变换的基本性质（线性，位移，z域尺度变换，时域卷积），傅里叶变换的基本性质。是一个不错的选题，GUI设计逻辑清晰，章节清晰，层次明了。(This project is based on MATLAB platform of digital signal processing simulation demonstration system. Digital signal is discrete signal. This design has a rich GUI human-computer interface, including four parts: convolution of discrete-time signal, Z-transform of basic function (unit step signal, pulse signal, oblique signal, sine cosine signal, exponential series signal), basic properties of Z-transform (linear, displacement, z-domain scale transformation, time-domain convolution), The basic properties of Fourier transform. GUI design logic is clear, chapter is clear, level is clear.)

基于Matlab的八度音阶发音演奏程序，包括9个源文件，七个音阶，一个频率调制，一个完成结果(Matlab based on the pronunciation of playing octaves procedures, including nine source files, seven scale, a frequency modulation, the results of a completed)

基于最小风险的bayes判别，可以用来判别位置类别的变量 十分好用！(Bayes discrimination based on minimal risk, can be used to determine the location of the variable type is easy to use!)
