农田多标记小图，可以用以极化SAR分解和半监督极化SAR分类。(Farmland multi-label small map, can be used to polarimetric SAR polarimetric SAR decomposition and semi-supervised classification)

说明：  进行三项交流电整流和逆变的论文，对进行变频控制其设计方面会有些帮助。(AC rectifier and inverter for the three papers, on the frequency control their design will be helpful.)

RS(255,223)与卷积码（2,1,7）的级联码，有编译码的各个模块(RS (255,223) and the convolution code (2,1,7) cascade yards, encoding and decoding of each module)

实现伪随机序列 关键词 随机矩阵 本源多项式 移位运算(Achieve the pseudo-random sequence Key words random matrix origin polynomial shift operator)

傅里叶变换的另一种表述，傅里叶变换的另一种表述，傅里叶变换的另一种表述(Another statement Fourier transform, Fourier transform another expression, another expression of Fourier transform)

说明：  直接转矩控制源代码,大家共同研究.m文件等.(Direct Torque Control of source code, everyone together. M files.)

该代码实现了“大津法”，也就是最大类间方差算法，完全由本人自己编写，结果很好。(The code of the " Otsu method" , which is the Otsu algorithm, written entirely by my own, good results.)

信号时正弦波加正态零均值白噪声，信噪比10db，信号频率2kHZ，采样频率100kHZ，数据长度N=256。 (1). 用周期图法进行谱估计。(Sine wave signal plus zero-mean normal white noise, SNR 10db, frequency 2kHZ, sampling frequency 100kHZ, data length N = 256. (1) with the periodogram spectral estimation.)

演示在给定初始位置和速度（含大小和方向）下verlet三粒子体系的二维演化运动情况(Demonstration verlet at a given initial position and velocity (including magnitude and direction) under the three-dimensional evolution of the particle system movement)

说明：  一个很好的核主成分分析matlab程序应用举例。该程序是在前人的核主成分分析程序基础上做了适当的修改产生的，可用于多维数据的降维和压缩处理。(A good kernel principal component analysis matlab application procedures, for example. The program is in the predecessors of Kernel Principal Component Analysis based on the procedures have been adapted to do so generated can be used for dimensionality reduction of multi-dimensional data processing and compression.)
