计算时间序列的熵信号，用以获取信号统计分析(Calculate the entropy of the signal time series, statistical analysis to obtain the signal)

Computation of the frequency response of the low- and high-pass filters that generate the orthonormal or semi-orthonormal (B-spline or dual) fractional splines of degree alpha, and of type + (causal), - (anticausal) or * (symmetric).(fract spline filters)

基于cpso文章，给出的一个matlab代码，添加测试函数即可运行。(Based on cpso, given a matlab code, add test function can be run.)

在快速傅里叶变换大的基础上以对信号进行短时分析，能画出三维瀑布图。(In the fast Fourier transform big on the basis of the signal is short analysis, can draw 3 d waterfall diagram )

本程序是mazen.O的经典论文：Performance Analysis of two-hop ralayed transmissions over rayleigh fading channels 的文章中所附的仿真图的程序，跑出的结果和文章中的附图是一样的！可以跑出里面的三张图，包括瑞利衰落下中继信道的中断概率的蒙特卡洛及公式的仿真，及选择不同的增益的性能差别曲线！ (This program is mazen.O classic paper: Performance Analysis of two-hop ralayed transmissions over rayleigh fading channels in the article accompanying the simulation of the processes, results and articles ran in the figures are the same! You can run out of the inside of the three figures, including the Monte Carlo simulation and the formula for the outage probability of Rayleigh fading relay channel, and select a different gain performance difference curves!)

此程序为信号阶次分析，主要针对汽车上振动噪声信号(Order this program for signal analysis, the main noise and vibration signals for the car)

lda基本思想是选择使得Fisher准则函数达到极值的向量作为最佳投影方向，从而使得样本在该方向上投影后，达到最大的类间离散度和最小的类内离散度(Linear classification algorithm)
