Hilbert-Huang Transformmatlab程序，及word版程序详单，这种算法用于机械行业故障诊断(Hilbert-Huang Transformmatlab procedures, and single-word version of the procedure in detail, the algorithm for fault diagnosis of machinery industry)

This function calculates the radial derivative of an input image. Input parameters: inputImage - the image to calculate the derivative from radialFilterLength - the length of the filter to use, total length will be 2*radialFilterLength+1 centerX and centerY - the point that is considered the center of the image, for the calculation minRadius and maxRadius - the minimum and maximum radius to calculate the angular derivative for. radialApproach - set to 1 to use a radius and angle search method, or 0 for a per-pixel approach

说明：  属于图像处理的基本，用MATLAB实现了Carlight算法。(Contains more than 100 kinds of basic image processing to achieve)

说明：  最近编写了一个程序，现在跟大家一起分享一下，多多指正。 改变曲线色彩(change the colour of the curve)

一款埃及学生用Matlab编的的基于PSO的PID整定程序，使用方法详见程序注释。(Tunning of PID controller using Bacterial Foraging Orientec by Particle swarm optimization My work has been accpepted in GECCO 2008 as Graduat Student workshop. I have used this techique in PID tunning and i got better result thatn BG and PSO Author: Wael Mansour (wael192@yahoo.com) MSc Student, Electrical Enginering Dept, Faculty of Engineering Cairo University, Egypt)

for Generating Random Number

说明：  面波反演的一个例子。。。。 里面有文件说明 相信大家会好好利用的(Surface wave inversion of a case in point. . . . There are documents that I believe we will make good use of the)

本书是比较好的matlab学习资料 可以帮助初学者掌握基本的编程，里边也包含了程序源是很方便的。(This book is a good matlab learning material to help beginners master the basic programming, which also contains the program source is very convenient.)

用matlab中的ode45的数值解法解给定初始条件的微分方程组(using matlab command ode45 to numerically solve ODE initial conditions)
