说明：  用java实现的UFO攻击游戏，里面有代码和可执行文件，操作简单，用鼠标左键单击UFO， 每击落10架之后，就会增加一架。(used to achieve the UFO attack game, and they code and executable files, simple operation, using the left mouse button click UFO, each downed 10, will be an increase.)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J) )

复杂网络中，对度分布特征的程序，源数据是邻接矩阵，运行简单，可得出两张图。(complex network, the degree distribution,and it is good job,you can get two graph)

图像融合工具箱先取两幅源图像相应的小波分解系数绝对值最大者的值作为融合图像的分解系数(先取两幅源图像相应的小波分解系数绝对值最大者的值作为融合图像的分解系数)

MATLAB 图像处理命令 相关命令： bwarea, bweuler, bwfill 功能： 增加或降低颜色映像表的亮度(matlab语句 ．applylut bestblk 4．brighten 功能： 增加或降低颜色映像表的亮度。)

用rayleighchan 函数仿真时要注意最后要做相位补偿（此问题是导师发现的） 程序步骤： ~产生随机序列 ~产生瑞利信道 ~调制 ~记忆信道特征 ~信号通过信道 ~相位补偿 ~加高斯噪声 ~解调 ~计算仿真误比特率 ~计算理论误比特率 ~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)

非常简单的卡尔曼滤波程序，便于大家学习卡尔曼滤波。(Very simple Kalman filtering program, easy to learn the Kalman filter.)

BPSK SYSTEM SIMULATION We simulate the generation of random variables r0 and r1, which constitutes the input to detector.The detector output is compared with the binary transmitted sequence and an error counter is used to count the number of bit errors. (BPSK We simulate the gen Kearney of random variables r0 and r1. which constitutes the input to detector.The de tector output is compared with the binary trans mitted sequence and an error counter is used to c been the number of bit errors.)
