法国人的emd算法，2007年的版本，镜像延拓，效果已经很不错了(French emd algorithm, the 2007 version, mirror extension, the effect is quite satisfactory)

Crystalline-Silicon Solar Cells

本程序功能为计算一阶双曲型偏微分方程的初值问题,采用蛙跳格式计算。(The program features to calculate the first order hyperbolic partial differential equations of the initial value problem, calculated using the leapfrog format.)

MATLAB基本图形图像处理操作，包含图像增强，图像分割，特征提取，图像识别，灰度处理线性算法，文字处理等多个压缩包(MATLAB image processing and basic graphics, including image enhancement, image segmentation, feature extraction, image recognition, linear gray-scale processing algorithms, word processing and other compressed)

自己编写的PSO算法优化BPM文件，用于时滞系统的辨识，辨识效果还不错。(This is a M file of BPNN I have written for the identification of delay systems identification.The simulation result shows that the method is valid.)

说明：  利用matlab编写的POS集群优化算法的工具箱，值得一看！(POS clusters prepared by using matlab optimization toolbox, worth a visit!)

主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)

MATLAB CODE FOR SEGEMNT

由Manchester大学编写的电阻抗成像系统软件 版本3.3(Manchester University, prepared by the electrical impedance imaging system software)
