gives a nice phase portrait of dynamical systems

基于simulink 框架的QPSK调制与解调(QPSK modulation and demodulation based on Simulink framework)

张正友相机标定程序 张正友摄像机标定法是一种简单实用的标定法，本次试验中共取用了同一摄像机从不同角度拍摄的六幅图像，经过Harris角点提取并优化从每幅图像中取十个特征点来进行摄像机标定（这十个点的世界坐标相同）。(Zhang Zhengyou camera calibration procedure Zhang Zhengyou camera calibration method is a simple and practical calibration method, this test CCP access to the six images of the same camera taken different angles, through Harris corner extraction and optimization take ten each image camera calibration feature points (the same world coordinate these ten points).)

留一法的matlab源代码，很不错的东西(Leave-one of the matlab source code, it is a good thing)

基于模糊控制的路边平行停车仿真matlab源代码，对于学习模糊控制理论有帮助。(Parallel parking simulation matlab source code is based on fuzzy control roadside, for learning fuzzy control theory help.)

LMS identification volterra order 2,degree 2

说明：  粒子群优化方法，并行计算，收敛速度快，利于全局优化，算法实现简单(Particle Swarm Optimization)
