本文简要介绍了语音信号采集与分析的发展史以及语音信号的特征、采集与分析方法，并通过PC机录制自己的一段声音，运用Matlab进行仿真分析，最后加入噪声进行滤波处理，比较滤波前后的变化。(This paper introduces the voice signal acquisition and analysis of the history and characteristics of speech signals, sampling and analysis methods, and through a PC, record your own voice, use of Matlab simulation and analysis, and finally adding noise filtering, comparing before and after filtering change.)

角锥体法后方交会，利用共线条件方程解算外方位元素(Resection pyramid method, the use of collinearity equation solver exterior orientation elements)

说明：  FM(Frequency Modulation) using simulink in Matlab.

实现机械故障在线检测， 实时控制，叶片裂纹的检测控制与报警。使得企业或者使用人员很方便的观测机械的故障并及时修正。(Mechanical fault diagnosis system)

飞行仿真模型,Matlab环境中运行，可实现快速仿真，性能分析(Flight simulation model, Matlab environment, run, fast simulation, performance analysis can be achieved)

fast calculation of image moments based on Fluss and Tuk s method described in "On the Calculation of Moments"

很不错的Matlab课件，从入门到进阶，尤其适合初学者，我不久前学习用过的。(Matlab is very good courseware, from entry to advanced, especially suitable for beginners, I used recently to study.)

对于线性系统，输入输出在某频率点为正弦，利用本程序可以得到改频率点的幅值比和相位差。data文件为两组数据，通过matlab读取xls文件，可以用来验证本程序。(For linear systems, input and output sine wave at a frequency point, the use of this program can change the frequency by the amplitude ratio and phase difference. data files for the two sets of data, read by matlab xls files, can be used to test the program.)

2-D FDTD code with simple radiation boundary conditions

Tranformasi wavelet merupakan perbaikan dari transformasi Fourier. Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi tentang kombinasi skala dan frekuensi
