我编的用于晶体的J-O 参数，对于稀土分析的研究者很有用啊(crystal series for the J-O parameters for the analysis of rare earth researchers useful ah)

Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立 叶变换。 由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。 已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉 及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal. Ye Bianhuan. Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution. It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve. And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)

说明：  用PSO蚁群算法改进的OMP神经网络具有良好的收敛性。非常实用(The OMP neural network improved by PSO ant colony algorithm has good convergence. Very practical)

说明：  直接序列扩频通信系统建模与仿真 PN码序列产生代码（matlab)(PN code sequence generated code (matlab))

运用matlab解多元多次方程方便快捷，实在不错啊 Multiple times using equation matlab convenient solution, it is good ah(Multiple times using equation matlab convenient solution, it is good ah)

快速多级子算法，类似与FFT的加速！ 快速多级子算法，类似与FFT的加速！多层快速多极子算法中的关键技术代码,希望对你们有用,不是很完整(fmm hopefast multipole method！ Very fast and complex！ fast multipole method！ Very fast and complex！)

线性调频步进脉冲信号的脉冲压缩实现，有结果运行截图(Chirp step pulse signal pulse compression implementation, the results of running screenshots )

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap5的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload chap5 source code here)

COUNTERDELETE(NAME) removes the counter specified by name permanently

一个完成调度车间的完整程序希望对大家有所帮助 (Scheduling a workshop to complete the full program we hope to help)
