求从1到20的阶乘，并且可以推广到N阶阶乘，。(Demand from 1 to 20 factorial, and can be extended to N-order factorial,.)

利用MMSE_MSE实现信道估计（matlab源代码）(channel estimation using MMSE_MSE)

说明：  matlab初学者入学指导，把这些题做完了，matlab基本已经入门了(matlab beginners guide school, finished these questions, matlab basically have a beginning)

说明：  matlab编程最好的入门教程，相当清晰，推荐学习！(The best entry-matlab programming tutorials, very clear recommendation to learn!)

自己写的一个关于非零频的LFM信号的产生，及下混频到零频的代码，有详细的注释(A non-zero frequency LFM signal generation, and under the mixer to the zero-frequency code, with detailed comments)

说明：  一种基于全变差的红外弱小目标背景抑制方法，效果不错(An infrared small target based background suppression total variation method, good results)

matlab在信号去噪过程中，运用小波包方法对信号进行降噪处理(matlab signal de-noising process, the use of the method of wavelet packet noise reduction processing on the signal)

说明：  电力系统拓扑分析、孤岛数，关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点，把开关元件作为拓扑图的支路，建立节点．支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与．或’’乘法运算，利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)

一个可以是的MATLAB仿真变得简单的使用仿真函数，可以不用建模仿真模型，而直接用函数就可以咯(Is the MATLAB simulation of an easy to use simulation function, you can do modeling and simulation models, and direct use of functions can be slightly)

各种常用数值计算的matlab程序，对数值算法的整理(Matlab numerical calculation of various commonly used procedures for the collation of the numerical algorithm)
