白噪声是一种很典型的噪声，经常被用作噪声模型使用，因此，掌握白噪声的性质尤其其频谱，自身相关性很重要。( noise)

说明：  确定性系统中建立一个跟踪系统让稳态误差变成0 ( This script demonstrates designing a tracking system with feedback and gain compensation to bring steady-state error to 0 and a settling time of 2.5 seconds. The response to a unit step is simulated and plotted to compare the system before and after compensation. This uses the STEP function from the system id toolbox and also ODE45 function to compute the step response.)

这是一个基于MATLAB编写的BUTTERWORTH滤波器的程序.其中从s域到z域的变换是自己编写的,代替了MATLAB中的系统BUTTERWORTH的系统函数(对于毕业设计的学生,比较有用!!)(based on MATLAB BUTTERWORTH prepared by the filter process. From which z's domain to the domain transform their own preparation, instead of MATLAB system BUTTERWORTH system function (for graduate design students more useful! !))

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)

this matlab code is for harmonic analysis in power networks for beginners.

曲线拟合和多项式拟合-2，主要用于工程计算，工程优化。(Curve fitting and polynomial fitting, is mainly used for engineering calculations, engineering optimization.)

its usage is in computer vision

matlab program for genetic algorithm use in artificial intelligent in power system optimization problem

网上下载的一个求取微分方程的程序，大家顶下(Download a program to strike a differential equation, we parietal)

灰度 GM（1.1）模型：灰色系统其内部一部分信息已知，另一部分信息未知或不确定。对既含有已知信息又含有不确定信息的系统进行的预测，也就是对在一定范围内变化的、与时间序列有关的灰过程进行 预测。(Gray GM (1.1) model of grey system: the internal part of the information known, the other part of the information is unknown or uncertain. In which there are both known information and uncertain for the prediction information system, is also the process of gray change in a certain range, with the time series related to Prediction.)
