基于矩量法的二维金属体散射程序，内含基本原理的介绍，matlab程序在附录(Method of Moments Based on the two-dimensional metal body scattering process, includes introduction to basic principles, matlab program in Appendix)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

用EWMA（garch（1，1））模型进行计算，rolling window的形式(use the method of rolling window size equals to 250, adopt EWMA model which also calls Garch(1,1) to calculate the Value at Risk)

多种用于分类的matlab代码，包含PCA,SVM,PLS-DA，KNN,SOMF等.(For various categories of matlab code, and contains the PCA and SVM, PLS- DA, KNN, SOMF, etc.)

this book has description of introduction to algorithms.

基于MATLAB的递推最小二乘法辨识与仿真，很实用(MATLAB-based parameter identification and simulation, very useful)

详细描述truetime工具箱的基本原理和用法，对初学者有帮助(Truetime a detailed description of the basic principles and usage of the toolbox, to help beginners)

ofdm是比较常用的调制方式，本文给出了子带的ofdm的matlab程序，希望可以帮助大家(OFDM modulation is more commonly used methods, this paper presents a sub-band of the OFDM matlab program, I hope you can help)

使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)
