经济类的实用的时间序列分析软件包，已经是目前最好的版本了。USCD_GARCH，可以研究非平稳时间序列数据。(kind of practical time series analysis software package, is the best current version. USCD_GARCH can study non-stationary time series data.)

设计一个滤波器滤除正弦信号中的噪声，还原正弦信号。正弦信号为sin100t，噪声信号是均值为0、方差为1的高斯白噪声。信号采样频率为2000 Hz。(The design of a filter to filter out the noise in the sinusoidal signal, restoring the sinusoidal signal. Sinusoidal signal sin100t, and noise signal with mean 0 and variance 1 Gaussian white noise. Signal sampling frequency of 2000 Hz.)

关于MATLAB的仿真的一些资料，非常完整，很不错全面的(MATLAB simulation on some of the information, very complete, very good overall)

数学建模赛题的Matlab解决程序，模拟车灯的映照情况(Mathematical Modeling Contest in the Matlab problem solving program to simulate the reflection of light conditions)

说明：  曲线拟合曲线拟合曲线拟合曲线拟合曲线拟合(Curve Fitting Curve Fitting Curve Fitting Curve Fitting Curve Fitting)

小波包变换可以对高频部分提供更精细的分解，而且这种分解既无冗余，也无疏漏，所以对包含大量中、高频信息的信号能够进行更好的时频局部化分析。(Wavelet packet transform can provide the high frequency part of the finer decomposition, and this decomposition is neither redundant nor oversight, so the signal contains a large amount of high frequency information can be a better time-frequency localization analysis.)

matlab - mapping 4 bit image to 8 bit and 8 bit image to 4 bit

我写的用于绘制绘制矩阵图形的小程序，要求matlab版本在6.0以上。(I write for rendering graphics rendering matrix of small procedures, requirements in Matlab version 6.0 and above.)

说明：  matlab编程实例一百个，非常有用的小程序，尤其是在图像处理方面。(matlab programming examples hundred, a very useful little program, especially in image processing.)

it contains many classic Test Problems for Unconstrained Optimization such as camel6,treccani,goldstein,branin, shubert1,Ackley,dejong,dejong1,dejong2, dpower,rastrigin,Griewangk,Schwefel, rosenbrock2 and step. the package have the contour and mesh figures of these problem. it also give m files of these problems,and you can easily get your view of figures.(it contains many classic for Test Problems Unconstrained Optimization such as camel6. treccani, goldstein, branin, shubert1, Ackley. dejong, dejong1, dejong2, dpower, rastrigin.
