NUMERICAL INTEGRATION: Implementation of the routine of order 8 and applied on the function sin(x), 0<=x<=pi Code is very understodable, and converge very fast.

周期函数的傅立叶级数与信号重构基波与谐波(Periodic function of the Fourier series and the fundamental and harmonic signal reconstruction)

说明：  摘要地层控制分析与设计问题 无人机（UAV）群系统实现时间。 研究了不同的地层。达到预定时间- 无人机的编队、编队协议各不相同。 首先是群系统，无人机的速度可能不同 当到达编队时。然后，基于共识的方法 用于处理时变信息的形成控制 无人机群系统的问题。必要和充分 无人机群系统实现时变的条件 提出了构造方案。(Abstract-formation control analysis and design problems for unmanned aerial vehicle (UAV) swarm systems to achieve time. varying formations are investigated. To achieve predefined time- varying formations, formation protocols are presented for UAV swarm systems first, where the velocities of UAVS can be different when achieving formations. Then, consensus-based approaches are applied to deal with the time-varyin formation control problems for UAV swarm systems. Necessary and sufficient conditions for UAV swarm systems to achieve time-varying formations are proposed.)

16qam的mimo系统信道估计误码率比较，方法是盲估计(Blind estimation of the 16QAM MIMO system channel estimation error rate comparison)

给定2个点坐标，计算其连线与水平方向的夹角，夹角范围[0,2*pi](failed to translate)

说明：  This code is to give a brief analysis of the famous GA alogrithm.

最新台湾中央大学HHT程序；包含一个实例，EMD工具和EEMD工具；可以求瞬时频率(A few examples of how to use these programs are given, with a given dataset “gsta.dat”, which is the annual mean global surface temperature anomaly. In “gsta.dat”, the first column is the time and the second is the corresponding data value.)

这是标准谱减算法和小波阈值降噪方法，虽然效果不太好，但是作为经典降噪方法，还是有很高的参考价值，也是此类文献引用最多的方法。(This is the standard spectral subtraction and wavelet thresholding method of noise reduction, although results are not good, But as a classic noise, or a high reference value, such literature is the most used method.)

基于压缩感知的图像分割，小波变换与OMP算法，最后由最大类间方差法作为分割手段(Compressed sensing image segmentation based on wavelet transform and OMP algorithm, and finally by the Otsu method as a means of dividing)
