In this simulation, a 2 x 2 MIMO system with BPSK modulation is used. Then, the algorithm of V(BLAST is implemented. After that, weight vector is produced using ZF, MMSE and ML detectors. Finally, the BER performance is plotted. A flat fading Rayleigh channel is assumed in this simulation.)

C语言实现直方图均衡化算法，结果与matlab函数一致，代码很简单，适合初学者。(C language implementation histogram equalization algorithm, the results are consistent with the matlab function, the code is very simple and suitable for beginners.)

雷达信号到达角估计的MATLAB代码，进行了多参数的对比仿真和结果比较(Radar signal DOA estimation MATLAB code for the comparison of simulation and multi-parameter comparison results)

这是用M语言写的程序，模拟猫追耗子的matlab程序(This is written in M language program, ，Matlab program to simulate the cat chased the mouse )

这是一个基于颜色直方图的粒子滤波目标跟踪的主程序，比较完整，供大家参考(This is a color histogram based particle filter tracking the main program, more complete, for your reference)

可以再研究非线性动力学问题中计算分形维数的Matlab程序(fractal dimension Matlab algorithm in nonliner dynaimcal systems )

这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (Note that this is not the function of function, but a statement about the problems in function. shortest () function there is no problem, I hope that in secshortest only a short time (or several roadcost () times the value of the same short-circuit), the result is several out, I carefully examined the process, it should be no problem. Therefore, in use, to be at a short circuit can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest. Some strange)
