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. )

Code in matlab about processing signals

一级倒立摆的m文件，包含lqr，pid等控制算法(The m file of a single inverted pendulum)

用matlab追迹子午光线，处理像差问题(Meridian ray tracing using matlab to deal with the problem aberration)

ofdma下行自适应资源分配算法仿真方面的几种算法对比。有图。直接点main文件即可运行(ofdma downstream aspects of adaptive resource allocation algorithm for simulation comparison of several algorithms. A map. Main file can be run directly point)

基于二维图像进行三维重建效果还可以，经测试误差较大(Two dimensional image reconstruction effect is also can be based on, after testing error)

该方法给出了一个CG算法求对称正定矩阵的线性方程的解，要求给出矩阵A、向量b和一个探测向量x0。(This method gives a CG algorithm for linear equations of symmetric positive definite matrix, requiring to give a matrix A, a vector b and a probe vector x0.)

Maximum Length PN sequences are binary sequence generators that are capable of outputting all possible combinations of binary sequences in 2^m-1 cyclic shifts, where m is the size of the LFSR (Linear Feedback Shift Registers ) used in generating such sequences. Terms like Psuedorandom binary sequences (PRBS) or psuedonoise sequences are also used to refer m-sequences.

说明：  轮式移动机器人的镇定，利用分段方法实现机器人镇定到x轴上(Stabilization of wheeled mobile robot, the use of sub-methods to achieve calm to x-axis robot)

利用卡尔曼算法做出的平衡车整套程序，可以给做平衡车初学者很好的借鉴( Kalman algorithms make use of the balance of the car the entire procedure can be done to balance the car a good reference for beginners)
