调频广播中，为了提高音频高频率端的信噪比，在发射端进行的预加重处理。(FM radio, in order to improve the high frequency end of the audio signal to noise ratio, performed at the transmitter pre-emphasis.)

对加噪信号进行奇异值分解。对奇异值计算其熵特征(Plus noise signal on the singular value decomposition. Calculate the entropy for the singular value feature)

利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现pca压缩图像，matlab语言(The interface graphics with input and output function designed by GUI of Matlab can realize the visibility of isometric line. The data and graphics compiled independently by oneself are worth learning. The realization of PCA compressed image and MATLAB language is very worthwhile.)

A color image is DCT transformed watermark embedded into the intermediate frequency coefficients to the effect of a good algorithm is the classic reference value has a strong image of yourself for the

牛顿迭代法，用于对通用多项式的计算，可自己设置处置，精度等(Newton iterative method for the calculation of general polynomials can set up their own disposal, precision)

Floyd最短路算法的MATLAB程序，可以求解最短路问题，比如旅行商问题，(The most short circuit algorithm Floyd MATLAB procedures, can solve the most short circuit problems, such as traveling salesman problem, )

说明：  通过调用IIR5函数对所给的信号进行滤波，其中通过fdatool 设计的直接1型切比雪夫滤波器的参数保存在coefficients1.mat文件中。(by calling IIR5 function as a signal to the filter, which it adopted fdatool design a direct-Chebyshev filter parameters stored in coefficients1.mat document.)

说明：  使用Visual C++ 调试DIB函数，详细了解其代码运行过程； 熟悉DIB函数库需要完成的关于位图操作的基本功能； 函数调试如：CreateDIBPalette（创建DIB调色板的函数），了解运行机制及过程过程 (Visual C++ debugging using the DIB functions to learn more about the code is running familiar with the library needs to be done DIB bitmap operations on the basic functions function debug as: CreateDIBPalette (DIB palette to create a function), understand the process of operational mechanisms and processes)

遗传算法工具箱，软件自带通用版，亲测可用(Genetic Algorithm Optimization Toolbox)

matlab依据椭球的高斯投影公式，将某一个点的经纬度坐标转化为横纵坐标的计算公式的m文件。输入形式为n*2的矩阵即可。(matlab based on the Gaussian ellipsoid projection formula, the latitude and longitude coordinates of a point into a vertical and horizontal coordinates of the formula m-file.)
