这是一个K中心点聚类算法C实现的,希望对大家有用(K this is a clustering algorithm C to achieve a focal point, and I hope useful for everyone)

总结了最基本和最常用的mattlab源码，很实用(Summarizes the most basic and most common mattlab source, it is practical)

matlab初学者资料 里面有M程序的详细文件 还有编程 直接运行即可(Matlab beginners material inside have M program detailed document and programming can be run directly)

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)

针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点，文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数，得到其能量分布集中于于信号的调频率曲线上的结论，此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计；然后通过解线性调频技术获得其初始频率和宽度的估计，仿真结果验证了本文算法的有效性。 (For the signal adaptive the chirplet decomposition of unknown parameters to achieve difficult to literature [1] proposed a new fast algorithm for chirplet decomposition. The algorithm makes use of the secondary phase of the calculated signal function, the conclusion focused on energy distribution curve to tune the frequency of the signal by the peak detection chirplet tune frequency, time center and amplitude estimates then by solving chirp technology to obtain the initial frequency and width is estimated that the simulation results demonstrate the effectiveness of the proposed algorithm.)
