在偏微分方程的数值求解中，有一类很重要的问题就是求解有奇异点的泊松方程，此程序是用C写的并行程序，能极大的提高泊松方程的求解(In the numerical solution of partial differential equations, there is a class of very important issues that have a singular point of solving the Poisson equation, this program is written in C parallel programs, can greatly improve the solution of the Poisson equation)

对信号进行小波变化，找出QRS波形，并利用不同方式进行消噪，从而用图形比较效果(It find the QRS wave of an input signal using wavelet transform and depress noise using several ways,so compare their figure.)

This program is the implementation of Pixel value differencing method

semi supervised Isomap,matlab codes.

压缩感知重构算法中的子空间追踪算法，是一种迭代贪婪算法。(Subspace pursuit algorithm is a kind of greedy pursuit algorithms in compressed sensing.)

基于二叉树定价原理的对于美式看涨期权和欧式看涨与看跌期权的模拟(Analog for the American call option and the European call and put options based on binary tree pricing)

说明：  三相电源的整流逆变，在某一时间点并网投入运行的一份仿真。(A simulation of three - phase power supply connected to the grid at a certain time.)

说明：  基于contourlet几何信息的图像去噪程序，该程序包括小波硬阈值方法，contourlet硬阈值方法，小波和循环平移结合的方法，contourlet和循环平移结合的方法，还有本文方法。(Based on geometric information contourlet denoising program that includes wavelet hard threshold method, contourlet hard threshold method, wavelet and recycling method of combining translation, contourlet and recycling method of combining translation, as well as the proposed method.)

频谱细化的程序，信号分析的强大工具，很好用！(Spectrum refinement of the program, a powerful tool for signal analysis, easy to use!)

演变过程 自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)
