说明：  该程序可以实现对于信号的时域参数提取以及信号的包络分析(The program can realize time domain parameter extraction of signals and envelope analysis of signals)

基于matlab的三维时域有限差分程序（cpml吸收边界），使学习时域有限差分方法的好资料。(Matlab-based three-dimensional finite difference time domain procedures (cpml absorbing boundary), so that learning FDTD good information.)

Pass the Images Through Optics -- Use a Gaussian "Aperture Function" This code segement can use a measured aperture function just as easily - simply replace the next five lines by "load measured_aperture" where measured_aperture is the measured function strored in ASCII and the data stored in the file measured_aperture.mat is a MATLAB .mat file that contains the matrix apfunction. (in MATLAB type "help load" for how to use load and look at the c and fortran code that shows how to read and write MATLAB .mat files). (Note: When the Point Spread Function is Gaussian, then so is the Aperture function) To simulate the effect of the tracker optics, each of the movie frames is now blurred using a 2-D FFT (Fast Fourier Transform). The first frame of the resulting image is shown in Figure 1.

atrous-toolbox,静态小波变换工具箱，matlab程序，里边有用于图像融合的融合程序(Atrous- toolbox, static wavelet toolbox, matlab, with a imagefusion program in it. )

根据lamda遗忘因子来确定均方误差的变化趋势，和alpha的变化，仿真效果好，达到理想的效果。(Lamda forgetting factor to determine the mean square error trends, changes and alpha, simulation results, achieve the desired results.)

this matlab code is for channel estimation. when the communication channel is time varying for correct detection of received information you should stimate the communication channel.

说明：  内点法求解IEEE-30bus电力系统经济调度问题(Interior Point Method for Economic Dispatching of IEEE-30bus Power System)

gm.11一个简洁的初级学习小程序，希望大家指正，向大家学习(Gm.11a simple primary study of small procedures, we hope that the correction, to everybody study)

希尔伯特变化的matlab实例，非常实用，而且已经测试通过了(Hilbert translation is used widely in signal areas. It has been considered as one of the most important tools.)

OFDN调制的Matlab实现，根据802.11协议的OFDM特性编写(Matlab OFDN modulation, according to the properties of OFDM 802.11 protocol)
