S-PID

根据一个数据的采样率、长度、通道数量，自动绘制频谱(DRAW SPECTRUM)

根据 DVB-T 欧洲标准写的一个OFDM matlab 仿真，其中包括发射器和接收器。文章中有matlab程式的详细介绍，有仿真方框图，还有每步的实验结果分析，特别适合OFDM的初学者。算是OFDM比较简单的一个入门介绍。英文也比较浅显，可读性很强(According to the European DVB-T standard to write a OFDM matlab simulation, which comprises a transmitter and a receiver. Article has a matlab program in detail, there is a block diagram of the simulation, as well as analysis of the experimental results of each step, especially for OFDM for beginners. OFDM considered a relatively simple introduction to. English is also relatively simple, readable)

运行程序得到微分方程中x1随参数omega变化的分岔图。omega的范围选取可以调节。(Run the program to be differential equations with parameters x1 bifurcation diagram omega changes. omega scope of selection can be adjusted.)

HHT源代码 做时频分析的同志们可以看一下 相当经典的例子(HHT time-frequency analysis of the source code to do the comrades can look very classic example of)

在图像精度评价中，主要用于比较分类结果和实际测得值，可以把分类结果的精度显示在一个混淆矩阵里面。混淆矩阵是通过将每个实测像元的位置和分类与分类图像中的相应位置和分类像比较计算的。(In the image to uate the accuracy, mainly for comparison of classification results and the actual measured value, the accuracy of the classification results are displayed in a confusion matrix inside. The confusion matrix is measured by each pixel position and image classification and classification in the appropriate location and classified as comparative calculations.)

matlab小波包工具箱的使用来分析信号，实现了一维去噪声的功能，恢复出了原始信号(wavelet packet Matlab toolbox used to analyze signals and realized the noise to a peacekeeping function, restoration of the original signal out)

MZM modulator Bias control two tones technique

是关于电磁建模的代码，用matlab语言编写(Is about the electromagnetic modeling code, matlab language)

说明：  双线性内插,图像放大缩小，简单容易学，好理解，上手快(Bilinear interpolation, image zoom, simple and easy to learn, easy to understand, quick)

K-means算法的实现,通过对没有标记的原始数据进行kmeans聚类得到的分类。(K-means algorithm to achieve)
