已知两个序列x[n]=cos(n*pi/2), y[n]=ej*pi*n/4x[n],绘制X(ejw)和Y(ejw)和幅度和相角,说明它们的频移关系(The known two sequence x [n] = cos (n* PI/2), y [n] = ej* PI* n/4 x [n], draw x (ejw) and y (ejw) and amplitude and phase Angle, suggesting their frequency shift relationship )

求星图中星象坐标的matlab函数，输入星图，利用交叉投影方法得到星象所在区域的四个顶点坐标和星象的质心，能够快速的求得星图星象的位置信息(Astrology chart for stars matlab function of the coordinates, enter the star maps, cross-projection method using astrology region and the four vertex coordinates of the mass center of astrology, the Express can find the location of star maps astrology information)

GPS卫星 L1波段的simulink仿真模型 包括CA码 载波 噪声 以及可以运行成功(GPS satellite L1 band Simulink simulation modelIncluding CA code carrier to noise and can run successfully)

说明：  本书是美国经典数字【信号与处理】的中文版。对于学习通信和信工来说非常有帮助(This book is the American classic digital signal processing】 【Chinese version. Work for learning communication and trust is very helpful)

该程序是基于matlab平台而编成的，解决分布拟合度卡方检验算法(The program is based on and derived from matlab platform to address the distribution of fit chi-square test algorithm)

关于图像的高斯处理的matlab程序，有效的进行高斯模糊(On the Gaussian image matlab processing procedures, the effective conduct of Gaussian blur)

自适应滤波的很多经典算法以及一些新的算法，FAP,APA,FAPA,RLS,LMS,NLMS(Many classical adaptive filtering algorithms as well as some new algorithms, FAP, APA, FAPA, RLS, LMS, NLMS)

解决TSP问题的TS算法MATLAB实现，其中加入了变异算法，当然也可以去掉这个步骤，调用TS_TSP(N, inStart, IsBianYi)，N是城市数目，inStart是起始城市的序号，IsBianYi就是选择变异否，如果为0则不要变异，否则就是结合变异算子的TS算法。 至于下面的参数可以自己调： T：总的循环次数； tabulength：禁忌长度； Pby：变异概率； (Solve the TSP problem MATLAB realize TS algorithm, which joined the variance algorithm, of course, this step can also be removed, call TS_TSP (N, inStart, IsBianYi), N is the number of cities, inStart is the serial number of the starting cities, IsBianYi is to choose variation has, if not for the variation of 0, otherwise, it is combined with mutation of the TS algorithm. As for the following parameters can be their own tune: T: total number of the cycle tabulength: taboo length Pby: mutation probability )

说明：  四种常见的归一化方法，归一化效果不错。应用在matlab环境下。(Four common normalization method, normalized results are good. Used in the matlab environment.)

说明：  在matlab中开发了一种如何使算法收敛更快，精度更高的算法，效果明显(developed in the Matlab how a convergence algorithm faster and more precise algorithms, obviously)
