求解量子力学的薛定谔方程，说明见readme.txt，使用matlab编制。可以现运行start.m(Solving the Schrodinger equation of quantum mechanics that see readme.txt, prepared using matlab. Can now run start.m)

Low-pass filters allow the low frequency components of an input signal to pass through while attenuating (reducing) high frequency components. Measurement noise fall into the high frequency range of the signal spectrum, while the underlying process signal usually lies towards the low frequency end. Thus filters that are used to remove noise from measurements are of the low-pass types. This program uses Chebyshev FIR low pass filter based on antenna theory approach to filter noise from human speech signal.

《数字信号处理教程——MATLAB释义与实现》的程序集，其中包括三部分。在examples子目录下本书全部例题的完整MATLAB程序；在subrtdsp子目录下是本书中自编的一些子程序，在运行例题程序时需要调用；这两个程序包是在学完本书后，读者能够读懂理解的。(dsk04 is a " digital signal processing tutorial- MATLAB Interpretation and Implementation" of the assembly, which consists of three parts. In all the examples subdirectory book example of a complete MATLAB programs in subrtdsp subdirectory is some self-compiled subroutines in the book, when running the example program need to call these two packages is in the completion of the book, the reader able to read to understand.)

最小二乘回归分析算法，进行逐步线性回归，实现了图像的加水印，去噪，加噪声等功能。( Least-squares regression analysis algorithm, Stepwise linear regression, Realize image watermarking, de-noising, plus noise and other functions.)

applies soft-threshold t to all elements of x and computes SURE

小波滤波，可用于心电信号、脉搏波信号的滤波(Wavelet filtering, can be used for ECG, pulse wave signal filtering)

将要分析的数据放在C盘的ELI.xls表的Bay表单中，根据数据多少调整读取范围（修改 b2:f16 此句) 结果有两种，一种是按数据计算权值求出的结果，另一种是参考建议值求出的结果。结果写入C盘的ELI表格，范围要手动根据数据多少调整(The data will be analyzed on the C disk ELI.xls Table Bay form, how much to adjust the data read range (change ' b2: f16' sentence) result, there are two, one is calculated according to weight data the results obtained, the other is the result of reference to find the recommended value. Results written to C drive of the ELI forms, the scope of how much to manually adjust the data)

我们编的MATLAB程序，实现了用最短路算法求最短路径。这是我们在学校国际赛模拟题做的东西，相信对数模很有用。(We compiled MATLAB program, using the shortest path algorithm to achieve the shortest path. This is our international competition simulation title in the school do something, I believe the number of modules useful.)

产生任意相关系数的多路高斯分布的噪声，用于模拟信号处理的噪声环境。(Generate multiple channals of noise with arbitrary cross-correlation coefficient )
