PCA

整数规划的一个求解方法（得到CUMCM一等奖）主要思想：找最大元之后的逐步互换求解，有点类似遗传算法(an Integer Programming Solution (with Into First Class) main ideas : after finding the greatest element gradually swap solution, it is somewhat similar genetic algorithms)

support vector pso examples

Ensure that Number.MAX_VALUE and Number.MIN_VALUE are extreme.

现代信号处理最后一次大作业，模糊函数的实现并画出3D图(The last time a large modern signal processing operations, the realization of the ambiguity function and draw 3D map)

MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式，并编写输出程序用以输出节点导纳矩阵、节点电压（包括电压的相角和幅值）、以及各支路的首端功率、末端功率和功率损耗(MATLAB implementation of the system flow calculation. MATLAB programming language requires the formation of the node admittance matrix, Jacobian matrix formed by modified Gaussian elimination method for solving equations, and write out procedures for the admittance matrix of the output node, the node voltage (including the voltage phase angle and amplitude), and the first end of each branch of power, end power and power loss)

说明：  通过matlab设计的GUI界面实现语音信号的实时录入和频谱分析和滤波等处理，并能够显示各阶段时域波形及频谱图，滤波器种类及参数可调(Through the GUI interface designed by matlab, the real-time input of speech signal, spectrum analysis and filtering are realized, and the time-domain waveforms and spectrograms of each stage can be displayed, and the types and parameters of filters can be adjusted.)

说明：  采用AR模型，估计功率谱密度，包含实测数据(The AR model is adopted to estimate the power spectral density, including the measured data)

用Matlab/Simulink的高压输电线路仿真模型，得到仿真数据，然后编程实现双端阻抗法测距！仿真结果表明，测距仿真是准侧的(Using Matlab/Simulink simulation model of high-voltage transmission lines to obtain simulation data, and then double-ended impedance programming ranging! Simulation results show that the simulation is quasi-ranging side)

说明：  基于主分类分析的SAR图像变化检测MATlt实验程序(Based on the analysis of the main SAR image classification change detection experiment)
