这是一个关于LDPC中的GIRTH4-COUNT的代码！( This program can produce the Parity Check Matrices of girth4-count codes, while Ref. remindes you that these codes are not good as the LDPC codes IEEE802.16e for continuous bits errors. )

图像索材，学习图像处理必须的一些常用图片，愿大家能轻轻松松学习图像！(Image cord material, learn to be a number of image processing used pictures, would like to learn that we can easily image!)

说明：  matlab编写的基于人工势场法的路径规划算法，可运行(The path planning algorithm written by Matlab can run)

matlab相关的程序，希望对大家有用，谢谢(matlab)

说明：  1．什么是卡尔曼滤波器（What is the Kalman Filter?） 2．卡尔曼滤波器的介绍（Introduction to the Kalman Filter） 3．卡尔曼滤波器算法（The Kalman Filter Algorithm） 4．简单例子（A Simple Example） 5. 用matlab做的kalman滤波程序,已通过测试 还有下面一个 Matlab源程序，显示效果更好。 (1. What is a Kalman filter 2. Introduction to the Kalman Filter 3. The Kalman Filter Algorithm 4. A Simple Example 5. Kalman filter code with matlab, has been tested.Another Matlab code shows better.)

有传统PID介绍，引申到改进算法，包括模糊控制，滑模控制等，配有大量实例，除利用simulink搭建外同时由c或matlab语言对照。(Traditional PID introduced extended to improve the algorithm, including fuzzy control, sliding mode control, Peiyoudaliang instance, in addition to the use of structures outside simulink matlab language by both c or control.)

直升机实验的仿真，利用的PID，LQR算法，可以当做练习学习(THIS is an helicopter simulate experiment, including PID and LQR algorithm.)

这是一些模糊控制的相关模块，希望对大家有用(These are related to fuzzy control module, want to be useful)
