从人的语音提取特征值的一种方法，lcp可能有些旧，但是还是不错的一种方法。(Extracted from the voice of a method of eigenvalue, lcp may be old, but still quite a way.)

复杂网络仿真及数据，matlab程序 电力网，公交网等电力网，公交网等(complex network)

说明：  实现端点检测的程序，可以通过图像查看仿真的结果(Endpoint detection process to achieve, you can view the simulation results by image)

说明：  这些程序是MIT学生学习Matlab时的教学程序，能面还有个pdf文档附有每个程序所实现的功能(This is the teaching codes at MIT for learning Matlab. hope it is helpful for you.)

说明：  振动信号模态参数识别预处理方法及ITD，STD(NExT method for modal parameter identification of vibration signal)

说明：  本文提出一种在原始视频DCT(离散余弦变换)与SVD(奇异值分解)域自适应嵌入水印的算法。算法首先将视频流分割成一个个场景,场景中的视频图像被变换到DCT-SVD域中,水印量化嵌入在最大奇异上,实现了水印盲检测。同时实验证明该算法在满足透明性要求下也满足一定的鲁棒性要求,能够抵抗低通滤波、中值滤波、椒盐噪声、高斯噪声、H.264压缩攻击以及统计攻击和帧剪切等攻击。(This paper presents an original video in the DCT (Discrete Cosine Transform) and SVD (singular value decomposition) algorithm for adaptive watermark embedding. Firstly, a video stream is divided into scenes, scenes of the video image is converted to the DCT-SVD domain, the watermark embedded in the largest singular quantification, the realization of the watermark signal. Furthermore, the experiments show that the algorithm meet the transparency requirements are met under certain robustness requirements, can resist the low-pass filtering, median filtering, salt and pepper noise, Gaussian noise, H.264 compression attacks and attacks and frame shear statistics attack.)

本文件主要内容是讲解关于matlab中对矩阵的运算等等(MATLAB matrix calculator)

program lyaponov method

The F5 algorithm embeds message bits into randomly-chosen DCT coefficients and employs matrix embedding that minimizes the necessary number of changes to embed a message of certain length.
