对比粒子群算法中不同的权重因子C1C2对算法收敛的影响(different C1、C2 to particle swarm optimization)

用MATLAB编写的时钟，希望对感兴趣的人有用(a clock code with matlab , hope useful to the one interested~)

采样定理的验证，即采样信号的频率大于等于原信号频率的两倍时才能准确的恢复原信号(Verification sampling theorem, the sampling frequency of the signal frequency is greater than or equal to twice the original signal in order to accurately restore the original signal)

电磁场仿真,有限长通电螺线管的仿真程序，利用网格计算实验效果好(Electromagnetic field simulation, finite-length solenoid power simulation program, the use of grid computing experiments good results)

说明：  matlab三维回旋仿真 使用了S函数，仿真时间300s，对于初学者有一定帮助(Matlab 3D gyration simulation uses s function)

说明：  GNSS软件接收机，用于对中频信号的处理及导航定位解解算(GNSS Software receiver.It is used to process if signal and solve navigation and positioning.)

线性调频信号脉压的编码程序，基础程序可以好好学习下，希望有帮助！(LFM pulse compression coding procedures, based on the program can learn under, want to help!)

matlab读取uff文件数据 Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data. It is not possible to write both sets of data to a single file. Written with a model file universal file are the geometry, elements and traceline data. However, just to add confusion, nodes and tracelines can also be written separately in their own file format.(Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data.
