有关傅里叶展开式的程序，速度非常快，而且还有相关的实例说明。(About Fourier expansion program, very fast, but also related examples.)

说明：  LMD，局部均值分解算法，主要用于对振动信号进行分析，不需要设置分解参数(LMD, a local mean decomposition algorithm, is mainly used to analyze vibration signals without setting decomposition parameters.)

基音检测： 对给定语料估计其基音周期。 要求用MATLAB或C语言实现有关基音检测算法，并给出检测结果与实验报告 实验语料：MaoYiSheng.raw 发音：“茅以升”；时长0.9s；采样率：8kHz；量化精度为16bits/sample；数据格式 LSB,MSB 分析帧长:20ms(160样点) 总帧数：45(Pitch Detection: For a given corpus to estimate the pitch period. Require MATLAB or C language on the pitch detection algorithm, and gives experimental results with the experimental report corpus: MaoYiSheng.raw pronunciation: " Mao Yisheng" duration 0.9s sampling rate: 8kHz quantify the accuracy of 16bits/sample data format LSB, MSB of frame size: 20ms (160 samples) the total number of frames: 45)

数字水印技术是近年来图像保护技术研究领域的一个热点, 本文提出了一种基于小波变换的图像数字 水印嵌入算法的Matlab 实现。实验结果表明, 该算法具有较好的视觉效果和透明性。(Digital watermarking technology in recent years is to protect technology research in the field of image a hot, this paper puts forward a method based on wavelet transform is the digital image Watermark imbedding algorithm Matlab. The experimental results show that the algorithm has good visual effects and transparency. )

vc和matlab混编技术之一：vc++基于com组件调用matlab的dll(One of vc and matlab mixed technology: vc++ DLL based on matlab com component calls )

为了过滤有色噪声，利用广义最小二乘进行系统模型的辨识(In order to filter colored noise, using generalized least squares models were recognition system)
