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)

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0, i.e. it returns the vector A=(a,b,c,d,e,f). To convert this vector to the geometric parameters (This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.

这个程序是一个模糊逻辑控制器，用来控制一个简单的水箱模型，比较简单，是我自己设计的，或许能够给大家一些帮助。(This process is a fuzzy logic controller, used to control a simple tank model, relatively simple, is my own design, may be able to give you some help.)

经典DOA估计算法matlab仿真，延迟相加，MUSIC，ESPRIT。有详细注释，步骤清晰，适合初学者学习(Classic DOA estimation algorithm matlab simulation, delayed addition, MUSIC, ESPRIT. There are detailed notes, clear steps for beginners to learn)

本程序计算金属包覆平板波导TE模等效折射率，然后计算其光场分布(This program calculates metal-coated plate waveguide TE-mode effective refractive index, and then calculate the optical field distribution)
